You do not need a string of marathons behind you. Strava’s analysis of the 2026 London Marathon showed that 37% of finishers were first-time marathoners. London offers one of the most welcoming and well-supported 26.2-mile courses in the world.

We are looking for regular runners who, with a year of structured training and sensible pacing, can absolutely complete the distance. If you are currently running regularly and are committed to a proper training plan, that is a strong foundation. We will support you with advice and encouragement throughout.

In a word, yes — and we would love to have you on the team. Our 2026 debut team included a cardiac arrest survivor who completed the course in fine style, and his achievement remains one of our proudest moments.

However, our overriding priority is that every Team SCA UK runner gets to the finish line safely. For that reason, we ask all survivor applicants to obtain written medical clearance from their cardiologist (or appropriate specialist) confirming they are fit to undertake marathon training and to race 26.2 miles.

We also ask that at least six months have passed since your cardiac event before applying, and ideally 18 months before race day. If you are unsure whether running is appropriate for you, your cardiac rehabilitation team or cardiologist is the right first call. You can read more about returning to normal activities after cardiac arrest in our information section.

We would rather lose a place than lose a runner.

The right answer depends on your child’s specific diagnosis, and you should always confirm restrictions with their cardiologist. That said, some common considerations apply across many inherited cardiac conditions.

Energy drinks and stimulants. Drinks high in caffeine or taurine — including most energy drinks — should be avoided by children with arrhythmia conditions. Caffeine raises heart rate and can provoke arrhythmias in susceptible individuals. This applies to strong coffee and some pre-workout supplements as well.

Swimming unsupervised. For conditions in which arrhythmias can be triggered by sudden immersion in cold water or exertion, particularly Long QT Syndrome type 1, swimming should always be supervised by someone who understands the diagnosis and can respond in an emergency. Your child should not swim alone.

Sudden loud noises. For some conditions, particularly Long QT Syndrome type 2, a sudden unexpected noise can trigger an arrhythmia. This is worth keeping in mind for alarm clocks, fireworks, and similar situations.

Competitive high-intensity sport. Whether this is restricted depends on the diagnosis and the individual. This should be discussed specifically with the cardiologist rather than assumed either way.

Fairground rides and extreme activities. High-adrenaline activities can trigger arrhythmias in conditions where the heart’s response to adrenaline is impaired. Ask the cardiologist specifically about these if they are relevant to your child’s lifestyle.

Gaming. Intense gaming can raise heart rate and adrenaline levels. There is limited evidence of specific risk for most conditions, but very prolonged, intense sessions are worth discussing with the cardiologist, particularly for conditions with adrenaline-related triggers.

Category: Sports

This depends on the underlying condition rather than the ICD itself. Clinical thinking has shifted considerably in recent years away from blanket activity restrictions for young people with cardiac conditions, recognising that the physical and psychological benefits of exercise are significant and that unnecessarily restricting activity can do real harm to a child’s development and wellbeing.

Many children with ICDs can participate in recreational sport and even competitive sport, depending on their specific diagnosis and risk profile. Others may be advised to avoid high-intensity exertion or contact sports where a blow to the chest is possible. These decisions should be made by a specialist paediatric cardiologist with experience of exercise and inherited cardiac conditions — not by a GP or the school, and not by applying generic rules from the internet.

If your child’s cardiologist recommends restricting sport, it is reasonable to ask what the evidence base for that recommendation is, whether it applies to all sport or only certain types, and whether the guidance would change over time. A second opinion from a specialist inherited cardiac conditions (ICC) service may also be appropriate if you feel the advice is overly restrictive without clear justification.

Whatever is agreed, make sure the school and any sports coaches are aware of the plan and know what to do in an emergency.

Category: Implantable Devices

Yes. Schools have a duty of care and cannot provide appropriate support if they do not know about a significant medical condition. Disclosing your child’s diagnosis means the school can put the right emergency procedures in place, ensure relevant staff are aware, and make any reasonable adjustments needed.

In practical terms, this means agreeing an individual health care plan (IHCP) with the school — a document that sets out your child’s condition, any medication, signs that something is wrong, what to do in an emergency, and who to contact. Schools are experienced in managing these plans and are legally required to support children with medical needs.

You should also confirm that at least one member of staff on site at any time knows about your child’s condition and is aware of the emergency plan. In secondary schools especially, where your child may not always be with the same teacher, it is worth thinking carefully about who holds that information.

What you share with other pupils and parents is your choice, and your child’s preference should guide that decision where possible. However, making sure the adults responsible for your child are fully informed is not optional — it could be life-saving.

Category: Practical Issues

Yes, most children with an ICD return to school, though the timing and any restrictions will depend on the underlying condition and your child’s recovery. Your child’s cardiologist will advise on when it is safe to return and what limitations, if any, apply.

Before your child goes back, it is important to meet with the school to share relevant medical information and agree an emergency plan. This should cover what to do if your child collapses, who is responsible for calling 999, whether a member of staff should be trained in CPR, and the location of the nearest AED. Schools in England are now required to have an AED on site.

Activity restrictions vary. Some children with ICDs can participate fully in PE and sports; others may need to avoid high-intensity or contact activities. This is a conversation to have with the cardiologist, not one to leave to the school to decide. A written medical summary from the cardiac team can be very helpful for the school to have on file.

It is also worth considering the emotional side of returning to school. Your child may feel anxious, self-conscious about the device, or worried about what peers will say. Speaking with a clinical psychologist before return, and giving your child some choice about what to share with classmates, can help significantly.

In the UK, CPR training is available through several organisations:

St John Ambulance (sja.org.uk) — offers face-to-face courses, online learning, and free resources including video guides.

British Red Cross (redcross.org.uk) — provides face-to-face and blended learning CPR courses.

St Andrew’s First Aid (firstaid.org.uk) — based in Scotland, provides first aid and CPR training.

NHS and ambulance services — many ambulance trusts offer free community CPR training. Contact your local ambulance service to find out what is available in your area.

Resuscitation Council UK (resus.org.uk) — provides guidance on CPR training standards and a directory of recognised training providers.

Free online resources — the British Heart Foundation’s Heartstart programme and Resuscitation Council UK both offer free instructional videos and guides. These are not a substitute for hands-on practice but are a useful introduction.

You do not need formal training to act in a cardiac arrest emergency — calling 999 and following the dispatcher’s instructions is sufficient. However, even a short training course significantly increases confidence and effectiveness.

The Circuit is the national defibrillator network for the UK, operated by the British Heart Foundation on behalf of NHS England. It is a register of publicly accessible AEDs \u2014 defibrillators that can be used by any bystander in an emergency.

When you call 999 about a cardiac arrest, ambulance dispatchers can access The Circuit to identify and direct bystanders to the nearest registered AED, potentially saving vital minutes.

You can also search for AED locations yourself at thecircuit.org.uk or via the NHS app.

If you have a defibrillator \u2014 in a sports club, workplace, school, church, or community building \u2014 registering it on The Circuit means it will show up to 999 dispatchers in an emergency. Registration is free and takes only a few minutes. It could mean the difference between life and death for someone in your community.

Life insurance is available after cardiac arrest and with an ICD, but it will typically be more expensive than standard rates and some providers may decline certain types of cover. The market varies considerably between insurers, so it is important to shop around and use a specialist broker where possible.

When applying for life insurance, you are required to disclose your medical history, including your cardiac arrest and any devices or conditions. Failing to disclose is likely to make any claim invalid. Insurers will usually ask for details of the event, the cause, your current medications, device type, and the results of your most recent cardiac review.

Some policies may be available at standard rates, particularly if the cardiac arrest occurred some years ago, the cause has been fully treated, you have a well-functioning ICD, and there are no other significant health conditions. Others will be offered at "loaded" (increased) premiums, or with exclusions for cardiac-related claims.

For those who cannot obtain standard life insurance, options include over-50s guaranteed acceptance plans (which do not require medical questions but typically pay a fixed sum) and specialist insurers who focus on people with pre-existing medical conditions.

The British Heart Foundation produces guidance on insurance for people with heart conditions. Specialist financial advisers experienced in this area can help identify the most suitable options.

A cardiac arrest does not mean life insurance is impossible — it means you need to look harder and possibly pay more.

Moderate alcohol consumption is generally considered safe for most people with ICDs, but there are some important considerations.

Alcohol can affect heart rhythm. Even in healthy people, heavy alcohol consumption can trigger atrial fibrillation ("holiday heart") and, in people with certain underlying conditions, ventricular arrhythmias. For people with inherited arrhythmia conditions such as Brugada Syndrome, alcohol — particularly in large quantities — can be a recognised trigger for dangerous arrhythmias and should be avoided or very strictly limited.

For most ICD patients, the general advice is to drink sensibly and within the recommended UK guidelines (no more than 14 units per week, spread across three or more days, with alcohol-free days). Binge drinking should be avoided.

Alcohol can also interact with some cardiac medications. For example, certain antiarrhythmic drugs and blood-pressure medications are affected by alcohol. Ask your pharmacist or cardiac team about any specific interactions with your medications.

If you are unsure what is safe for your specific condition, discuss it with your cardiologist or device clinic. They can advise based on your diagnosis, your device settings, and the medications you take.

Doctors use guidance published by the DVLA when assessing whether a patient is medically fit to drive following a cardiac arrest, arrhythmia, or ICD implantation. This guidance sets out recommended periods of driving restriction based on diagnosis and treatment, and distinguishes between Group 1 licences (cars and motorcycles) and Group 2 licences (lorries and buses, which have stricter requirements).

For most people following a cardiac arrest or ICD implantation, a period of driving restriction is mandatory. The length of restriction depends on factors including whether an ICD was fitted, whether the arrest was due to an identifiable and treatable cause, and whether there are ongoing arrhythmia concerns. Restrictions typically range from one month to up to two years for Group 2 licence holders in some circumstances.

The responsibility for notifying the DVLA of a relevant medical condition rests with you as the licence holder, not your doctor. Your cardiologist or GP can advise you on whether and when you need to notify the DVLA, but you must make the notification yourself. Driving before you are medically and legally permitted to do so can invalidate your insurance.

For full clinical guidance, see the DVLA’s published Assessing Fitness to Drive guidance for medical professionals. For patient-facing information about driving restrictions after SCA, see our dedicated driving FAQs.

There is no specific legal requirement for employers to provide defibrillators in the workplace. The Health and Safety Executive’s syllabus of first aid training for offshore installations does include the use of defibrillators, but this is not extended to onshore first aid. However, the Health and Safety (First-Aid) Regulations 1981 do not prevent an employer from providing defibrillators that could benefit both their employees and the public.

For information on workplace health and safety legislation please refer to the Health and Safety Executive’s website.

It is very unlikely that someone in the UK who acted in good faith when trying to help another person would be held legally liable for an adverse outcome. No such action has ever been brought against someone who performed CPR and, in general, the courts in the UK look favourably on those who go to the assistance of others.

Resuscitation Council UK has published detailed guidance on the legal status of those who attempt resuscitation. This provides answers to most of the commonly asked questions on the subject.

Category: Practical Issues

No. In the UK, it is very unlikely that someone who acted in good faith when trying to help a person in cardiac arrest would face any legal liability. No action has ever been successfully brought against a bystander who performed CPR in the UK. The courts look favourably on those who go to the assistance of others in an emergency, and performing CPR on someone in cardiac arrest cannot make their situation worse. If you are concerned, the important thing is simply to act — calling 999, starting CPR, and using a defibrillator if one is available. For specific legal questions, the Resuscitation Council UK provides further guidance.

Yes. Intimacy is a normal part of life and most people with an ICD can resume sexual activity when they feel physically and emotionally ready. There is no standard waiting period, though your cardiologist or cardiac nurse may give you specific guidance based on your individual situation.

If you have concerns about intimacy, the risk of a shock during sex, or the impact on your relationship, these are legitimate topics to raise with your clinical team. Many people find them difficult to bring up, but your cardiac nurse or cardiologist will have had these conversations before. You can also find peer support through SCA UK.

Most people with an ICD can continue or return to the activities and hobbies they enjoyed before, including walking, cycling, swimming, golf, gardening, and many sports. The device is designed to allow your heart rate to rise normally during exercise without delivering unnecessary treatment.

Whether any specific activities need to be restricted depends on your underlying condition rather than the ICD itself. Your cardiologist will advise you on anything to avoid. If you are unsure about a specific activity, ask before resuming rather than avoiding everything out of caution.

Category: Practical Issues

Yes, you can ride a bike with an ICD. However, if using a stationary exercise bike, keep the wheel magnet at least 15cm (6 inches) away from your heart device. Always check with your doctor or device clinic if you have any specific concerns.

For most people with an ICD, moderate resistance exercise including bench-pressing is not ruled out, but there are important considerations depending on when you were implanted and what your underlying condition is.

In the weeks immediately after implantation, lifting heavy weights is restricted. Sudden forceful use of the pectoral muscle on the side of the device can place stress on the lead before it has fully bedded in, and your clinic will give you specific guidance on arm and shoulder movement during this initial period. Most people are asked to avoid raising the arm on the implant side above the shoulder or lifting anything heavy for four to six weeks.

Once fully healed, whether you can return to weightlifting depends largely on your underlying condition rather than the device itself. High-intensity exercise raises heart rate significantly and in some conditions this can increase arrhythmia risk. Your cardiologist is the right person to advise on what intensity is safe, and an exercise test may be used to assess your individual response.

There is also a practical consideration with heavy pressing movements: repeated significant pressure directly over the device site, or any exercise that causes the device to shift or become uncomfortable, should be discussed with your clinic. A protective vest or pad may help in some situations.

An abdominal implant site may require some additional caution in contact sports such as rugby, martial arts, or football, where there is a risk of a direct blow to the abdomen. Whether specific activities are restricted will depend on your underlying condition and your cardiologist’s advice, not solely on the implant location.

Discuss any sport or physical activity you want to continue or take up with your cardiologist before returning. A body protector or pad worn over the device may be recommended in some circumstances.

Your heart device monitors your heart rhythm and delivers therapy wherever you are in the world. There are no specific restrictions on travelling abroad with an ICD, though there are some practical considerations to plan for.

Take your device ID card with you at all times. This identifies your device to medical staff if you need treatment abroad and helps at airport security. Make sure you have comprehensive travel insurance that covers your cardiac condition. Let your ICD clinic know you are travelling, particularly if you are going for an extended period, as remote monitoring may need to be adjusted for a different time zone or if you will be away from your base station.

If you need medical attention abroad, inform the treating team that you have an ICD and carry the manufacturer contact details with you. In an emergency, they can provide technical support to local clinicians.

Before travelling, make sure you carry your device ID card at all times, as it contains important information about your device and may be needed at port security. It is also worth contacting your travel insurer to confirm your cover — see our FAQ on travel insurance for more information. Let your device clinic know you are travelling so they can advise on remote monitoring arrangements if needed.

Skiing will not interfere with your ICD. Whether you are able to ski depends on your overall medical condition and your cardiologist’s guidance, not the device itself.

Most people return to skiing and other physical activities after a full recovery from ICD implantation. Discuss any concerns with your cardiologist before you travel, particularly if you have an exercise-triggered condition, or if high altitude is relevant to your heart condition.

Category: Implantable Devices

Yes. Riding on a train or tram poses a very low risk of interference with an ICD. However, we recommend talking to your cardiologist before your journey up the mountain, as there are lower oxygen levels at high altitudes.

Category: Implantable Devices

Yes. In the UK you are legally required to inform the DVLA if you have a condition or device that may affect your ability to drive safely. Having an ICD is a notifiable condition.

For Group 1 licences (car and motorcycle), there is typically a period of driving restriction following ICD implantation (usually six months), and further restrictions may apply if your device delivers a shock. For Group 2 licences (lorries and buses), the restrictions are stricter and in many cases permanent.

You should notify the DVLA using the appropriate medical questionnaire. For most people with an ICD, this is the DEFIB1 form, available on GOV.UK. If you drive a coach, bus or lorry (Group 2 licence), use the VOCH1 form instead. Your cardiologist or device clinic can support you with this process and provide any necessary medical information. You should also inform your motor insurer, as failing to disclose a relevant medical condition can invalidate your policy.

Always check the current DVLA guidance, as the rules are updated periodically. The full guidance is available at www.gov.uk/dvla/medicalenquiries.

It depends on what kind of boxing you mean.

Fitness boxing (bag work, pad work, shadowboxing) is generally considered acceptable for most people with ICDs, provided your cardiologist has cleared you and you’re past your initial recovery period. It’s an effective cardiovascular workout and vigorous exercise alone won’t trigger your device inappropriately.

Contact boxing (sparring or competitive bouts) is a different matter. The primary concern is direct impact to your ICD site, typically the upper left chest. A hard blow to that area could potentially dislodge a lead or damage the device housing. There’s also a broader consideration with contact sports: repeated physical trauma raises your overall risk profile, particularly if your underlying condition involves arrhythmia.

Most cardiologists will advise against competitive or contact boxing. If boxing is important to you, it’s worth having a frank conversation with your cardiology team about the specific type, your underlying condition, and what a safe approach might look like.

If you do train in a boxing gym, specialist protective vests that shield the ICD site are available and worth considering.

In the UK, holding an ICD will prevent you from holding a Group 2 licence, which covers lorries (LGV/HGV) and buses (PCV). If you currently hold a Group 2 licence, having an ICD implanted will typically result in its revocation by the DVLA.

This can be a significant and distressing consequence for professional drivers, and it is worth discussing the implications with your cardiologist before implantation where possible. In some circumstances, alternatives to ICD therapy may be considered, though this is always weighed carefully against the risk of sudden cardiac arrest.

If you drive professionally and have been told you need an ICD, speak to your cardiologist and contact the DVLA for specific guidance on your situation. Occupational health support from your employer may also be available.

Category: Implantable Devices

In the UK, having an ICD or the underlying heart condition that led to its implantation will almost always prevent you from holding a Civil Aviation Authority (CAA) medical certificate, which is required to fly as a pilot of any category.

This applies to Private Pilot Licences (PPL), Commercial Pilot Licences (CPL), and Airline Transport Pilot Licences (ATPL). The CAA assesses each case individually, but conditions such as ventricular arrhythmia and ICD implantation are considered disqualifying in the vast majority of circumstances due to the safety implications of sudden incapacitation at altitude.

If you are a trained pilot and are facing ICD implantation, it is worth seeking specialist aviation medical advice early — ideally from an Aeromedical Examiner (AME) — before any decisions are made, so that all options are fully understood. In very limited circumstances, some pilots may be able to fly in certain categories with specific conditions, but this is rare and assessed on a case-by-case basis.

Yes. Remember to discuss exercise with your doctor, and follow their guidelines based on your own health needs. It’s always best to ease back into a fitness routine. Walk before you jog, jog before you run, etc…

Category: Implantable Devices

Yes. Exercise is actively encouraged for most people with ICDs. Physical activity supports heart health, mental wellbeing, and recovery. An ICD is not implanted to limit you; it is there to protect you if a dangerous arrhythmia occurs.

The type and intensity of exercise that is appropriate depends on your underlying condition and your cardiologist’s guidance. Most people can resume moderate exercise such as walking, swimming, and cycling after a full recovery from the implant procedure. Some may be advised to avoid very high-intensity exercise or competitive sport, particularly if they have an exercise-triggered arrhythmia condition.

Cardiac rehabilitation is an excellent starting point for rebuilding fitness safely after cardiac arrest or ICD implantation. Ask your GP or cardiac team for a referral, particularly if you were not automatically offered one. In the UK, cardiac rehab is most consistently commissioned for people who have had a heart attack, and survivors with no identified cause (idiopathic) or an arrhythmia-related cause are sometimes not offered it. Be persistent.

Skydiving is one of the few activities where the answer is more cautious than a straightforward yes. Most cardiologists advise against it for people with an ICD, and it’s worth understanding why before making any decision.

The main concerns are:

Physical impact on landing. Even with good technique, landing places sudden mechanical stress on the body. If your leads haven’t fully settled, or if there’s any risk of the ICD shifting, this is a genuine consideration.

Altitude. Modern ICDs are tested to function at altitude, but freefall from standard jump heights (3,000-4,000m) involves rapid pressure change. Whilst this is unlikely to affect device function, it has not been formally studied in clinical settings.

Emergency access. If your ICD delivers a shock during freefall, you’ll be at altitude and potentially incapacitated. Immediate medical response would not be possible.

That said, “not advisable” isn’t the same as “absolutely prohibited.” Your specific situation (device type, underlying condition, and how well your arrhythmia is controlled) matters significantly. Any decision should be made directly with your cardiologist, and it’s also worth contacting your device manufacturer about altitude tolerance for your specific model.

Yes. Swimming is safe with an ICD once you have fully healed from the implant procedure. Most people are advised to avoid swimming for around four to six weeks after implantation to allow the wound site to heal properly and to reduce the risk of lead dislodgement while the leads are bedding in.

After recovery, there are no specific restrictions on swimming for most ICD patients. If you swim in open water, it is sensible to go with a companion, as it is with any open water swimming.

If your cardiac arrest was caused by an inherited condition such as CPVT or Long QT Syndrome, where exercise or cold water can trigger arrhythmias, discuss specific restrictions with your cardiologist.

In the UK, driving after receiving an ICD is governed by DVLA regulations, not solely by your doctor’s assessment.

For Group 1 licences (car and motorcycle), a driving ban of at least six months typically applies following ICD implantation. If your ICD delivers a shock that causes or could have caused incapacity, a further period of restriction applies. Once the restriction period has passed and your cardiologist confirms your condition is stable, you can usually resume driving.

For Group 2 licences (lorries and buses), the restrictions are much stricter. Having an ICD typically results in permanent revocation of a Group 2 licence in most circumstances. This can have significant implications for professional drivers.

You are legally required to notify the DVLA and your motor insurer. Your cardiologist or device clinic will advise you on when it is medically appropriate to resume driving, but the final determination is made by the DVLA. Always check the most current guidance at www.gov.uk/dvla/medicalenquiries.

Yes, most people with an ICD can play football, though the level of contact involved is worth thinking through.

Association football involves running, jumping, heading and occasional physical contact. For most recreational players with an ICD, this is manageable once your cardiologist has cleared you to return to sport. Your device is designed to work during vigorous physical activity and won’t fire inappropriately during normal exertion.

The main consideration is impact to your device site. A collision or stray elbow near your upper left chest (where most ICDs are implanted) carries a small risk of lead dislodgement. This doesn’t mean you can’t play; it means it’s worth thinking about the level.

Recreational five-a-side or Sunday league: generally lower risk, and many people with ICDs play regularly.

Competitive or high-intensity football: worth a more detailed conversation with your cardiologist about your specific condition and device.

Heading the ball is separately under review in football for neurological reasons. If you have any cognitive or neurological concerns following your cardiac arrest, raise this with your care team.

Specialist protective vests that cover the ICD site are available if you want added reassurance.

Yes. Sexual activity is a normal and important part of life, and having an ICD shouldn’t stop you.

From a physical standpoint, sex is roughly equivalent in exertion to climbing two flights of stairs, moderate activity that most people with ICDs can manage comfortably once they’ve recovered from their procedure. Your cardiologist will advise when it’s safe to resume, typically once you’re comfortable with light to moderate physical activity.

A common worry is whether a shock during sex could harm a partner. The honest answer: it’s extremely unlikely to cause any harm. If your ICD were to deliver a shock, a partner in physical contact might feel a mild tingle, but not a painful or dangerous shock. This is a widely asked question and one worth discussing openly with your care team if it’s causing anxiety.

Many people find that worry about the ICD itself affects confidence more than any physical limitation, and that is completely normal. SCA UK’s peer support community includes people who’ve navigated exactly these concerns. You’re not alone in having them.

Full guidance on intimacy and ICDs, including information for partners, is on our Sex and Intimacy After Cardiac Arrest page.

If you have specific concerns about your situation, speak to your cardiologist or specialist nurse.

Wherever you travel, your heart device monitors your heart and provides therapy whenever it is needed. You can travel knowing that support for your heart device is available around the world. Your doctor may also be able to check your heart device remotely, so it may be a good idea to let your doctor know when and where you will be traveling.

There are no restrictions for swimming in pools with your device and they are safe as long as there is no electrical current leakage into the water.

Golf is generally fine for most people with an ICD, but timing matters, particularly in the first weeks after implant.

The main consideration is lead dislodgement. ICD leads take four to six weeks to fully bed in after surgery. During that period, overhead arm movements (including the golf swing) carry a small risk of displacing a lead. Most cardiologists advise waiting until your first post-implant check-up and getting formal clearance before returning to the course.

Once cleared, the majority of people with ICDs play golf without any problems. Your device won’t interfere with your swing, and moderate exercise such as walking 18 holes actively supports cardiovascular recovery.

A few practical points to bear in mind:

• Carry your ICD device card and an emergency contact when you play
• Electric golf buggies and trolleys won’t affect your ICD, but keep your device away from powerful motors on greenkeeping machinery
• If you experience dizziness, palpitations or breathlessness on the course, stop and rest, and contact your cardiology team if symptoms persist

Always check with your cardiologist before returning to sport after a cardiac event or device implant.

Ask your doctor about this one before you ride. Some coasters restrict people with heart conditions. Other times shoulder harnesses can be very uncomfortable on the implant site, or even cause damage.

It may be possible, it depends on whether you satisfy the criteria for Section 88 of the Road Traffic Act.

See “What is Section 88” for more information.

Category: Driving

You can find information and the status of your driving licence by using the government licence check facility.

You will need your driving licence number, national insurance number and postcode.

You can see details about who the licence is for when it is valid from/to, the current status, what vehicles you can drive, any penalties or disqualifications.

You can also get a code so that you can share your licence details with another party such as an employer or car hire company.

The official advice is that you should inform your insurance company of your heart condition and implant (ICD/pacemaker) if you have one.

However, from our members experience most insurance companies do not seem to be interested in the fact that you have had a cardiac arrest. If you have a valid licence to drive then they are generally happy to take your money and insure you.  

Of course, if you are on a prolonged suspension and your car isn’t going to be used you may wish to speak to them to alter your level of cover and potentially save a few pounds.

If at any time you receive an appropriate shock from your ICD i.e. one that is correcting a potentially fatal arrhythmia, you must surrender your licence and stop driving for 6 months.  

If you were incapacitated i.e. went unconscious whilst you received the shock the suspension is 2 years. This may be reduced to 6 months if your cardiologist takes steps to prevent any further events requiring a shock eg starting or adjusting medications.

If you receive an inappropriate shock i.e. the shock was unnecessary, then you will receive a 1 month suspension.

If you are driving whilst you receive a shock you should stop as soon as is safe to do so, and should not continue until the cause of the shock has been investigated.

For more information about shocks see our ICD shocks page.

Section 88 refers to a part of the Road Traffic Act that may allow you to continue driving even if you do not physically have your driving licence.

There is a provision in the law, under section 88 that MAY allow you to drive while the DVLA process your application.

You must meet the following criteria:

• You must be confident that your application will not be refused due to any medical condition you declared.
• You must have held a valid driving licence and only drive vehicles you are qualified to drive.
• You must meet any conditions specified on your previous licence
• You must have sent your fully completed application (re-application) to DVLA in the last 12 months
• Your licence has not been refused or revoked
• You are not disqualified from holding a licence by a court

If you fulfil these points you can drive again even though your licence has not been returned to you.

DVLA cannot tell you if this section of the law applies to you.

For more information read the government leaflet on Section 88

Once your advised period of voluntary surrender has elapsed you will be able to re-apply again and have your licence returned to you.  

You can find information on this process on the government website and a link to download the relevant form.

Once you have mailed this you will receive a letter from DVLA stating that they have written to your consultant with an expected 6-week turnaround.  You do not need to do anything further other than call them back on several occasions as this part of the process takes a long time!

The DVLA will send your cardiologist forms to get more information about your cardiac status.  Your cardiologist will need to sign these forms to say they should issue you with a licence. This all takes time, and it’s a good idea to chase your cardiologist to make sure you’re not forgotten.

It’s also worth starting the process a good 8 weeks before the date your period of driving restriction ends.

If your licence was revoked, as opposed to voluntarily surrendered, you may find that the process to get your licence back longer and more arduous.

In the SCA UK Facebook Group we are seeing an increasing number of members who get their licence revoked when they voluntarily surrender it.

At this time it is not clear why this happens as we have seen members with apparently similar circumstances have different outcomes.

The DVLA can revoke your licence on medical grounds and it may be the differences in the details that they make their decision but for now, it is a bit of a mystery.

Our only advice would be to not use the online form but as soon as possible fill in the paper forms and send in your licence stating that you are voluntarily surrendering your licence. This is because anecdotal evidence from the group indicates that if you use the online form it appears you’re more likely to get your licence revoked.

Remember if your license is revoked you cannot use Section 88 rules to drive until your license is reinstated.

The date of your suspension will usually start from the date that you have any remedial work or get a formal diagnosis of a condition, not necessarily the date of your cardiac arrest.

For example, if you have a cardiac arrest and 2 weeks later get an ICD implant, then the suspension will start from the date of the implant, not the arrest.

If you have a heart attack as the cause of your cardiac arrest, the problem is often looked at and dealt within a short time frame (same day) so the suspension will start from that day.

Category: Implantable Devices

It will largely depend on your individual circumstances and medical conditions but common suspension periods are as follows:

If you had a heart attack as the cause of your cardiac arrest and it was remedied with medications and/or stents then the suspension period is 1 month.

If you had to have an ICD fitted then the suspension period will be 6 months from the date of the implant. If you have any shocks further suspensions will apply and the length will vary depending on a number of factors. See “Can I drive if I get a shock from my ICD” for more information.

You may also have to temporarily stop driving if your anti-arrhythmic medications are changed, typically for 1 month.

If your driving licence was revoked you’ll have to wait until all medical enquiries are complete. You will also need to have your driving licence back before you can start driving again.

You can check the DVLA information for medical professionals regarding assessing fitness to drive here, and this shows the rules regarding whether you can drive or not and if not, for how long.

This is one for your doctor.

You should be assessed by your doctor using these guidelines which determine the rules for assessing drivers with cardiac conditions.

Many of the conditions listed will mean that there will be some period of suspension, but you may be allowed to drive again if you can meet certain conditions including assessment by a specialist cardiologist.

However, if you have an ICD implanted you will not be able to drive an HGV or commercial vehicle.

No.

The length of your suspension can vary depending on a number of factors including but not limited to cause of your cardiac, remedial actions taken, subsequent or other conditions.

It may seem tempting to compare one person’s case with another but it is often difficult to do so because of not having the full facts about a person’s situation.

If you are unable to drive because of your cardiac arrest and you are in a position to return to work, you may apply for the “Access to Work” scheme which may help with other transport costs, such as public transport or even private taxi’s.

For example, a member of SCA UK who was a teacher when she had her SCA was unable to return to work because she had an ICD fitted and this meant a driving suspension period of 6 months. She lived in the country and there was no suitable public transport to get her to her school. The “Access to Work” scheme gave her a grant to allow her to get a taxi to and from her place of work.

If you can get to work by public transport you might be able to get reduced price travel such as a Disabled Person’s Railcard. If your licence has been revoked for medical reasons, you are entitled to a free bus pass in most areas. In Northern Ireland, you can get a SmartPass giving you half price travel. In London, you can get a Freedom Pass. Apply through your local council.

If you are worried about the safety of someone’s driving, it can be a tricky subject to talk about. But it’s vital to make them aware of your concerns, not just for their safety, but for the safety of others on the road.

If a person has been driving for many years it can be hard to suddenly stop, and it can change the way they see themselves. So they may need support and guidance from family, friends and professionals.

Sometimes survivors find it difficult to recognise the effects of the event. It can also affect your judgement and, in rare cases, someone can be unaware they have a disability. This is called anosognosia.

Family members and professionals may need to remind them that they can no longer drive because of the potential risk to themselves and others. You could read this together and talk about the other ways of getting around, and plan some of the journeys they might want to make using alternative types of transport.

If you feel that the person is not safe to drive and they refuse to stop driving, you can write to the DLVA in confidence online.
