FAQ

Stop exercising and seek advice if you experience chest pain or tightness, dizziness or light-headedness, unusual shortness of breath out of proportion to the effort, palpitations or a noticeably irregular heartbeat, or a shock from your ICD.

These symptoms do not necessarily mean something is wrong, but they should be assessed before you continue exercising. Contact your GP, cardiac rehab team or device clinic and describe what happened, including what you were doing at the time. If you receive an ICD shock, contact your device clinic or cardiology team the same day. If symptoms are severe or do not settle with rest, call 999.

Once you have been checked, most people are able to return to activity with adjusted guidance rather than stopping altogether.

Yes, you can ask for it, and you should. In practice, cardiac rehabilitation in the UK is most consistently offered to people recovering from a heart attack. If your cardiac arrest was caused by an arrhythmia, an inherited condition, or had no identified cause, you may not be referred automatically.

You are entitled to ask for a referral regardless of the cause of your arrest. Speak to your cardiologist, cardiac nurse or GP, and be persistent. The supervised exercise, education and psychological support that rehab provides are valuable for all cardiac arrest survivors, and some areas run programmes that accept a wider range of patients.

If you are turned down, ask why, and ask what alternatives are available locally. Our community includes many survivors who only got a rehab place because they pushed for one.

Category: Treatment

For most people, light activity such as short walks and gentle stretching is encouraged within days of leaving hospital. More structured exercise usually begins after a cardiac rehabilitation assessment, typically four to six weeks after the event. A return to sport needs explicit clearance from your cardiologist, and the timescale varies by activity.

If you have an ICD, avoid overhead arm movements and strenuous upper body exercise for the first four to six weeks after implantation, so the leads can settle. Your device clinic will advise you specifically.

Do not wait until you feel completely well before starting to move. Prolonged rest does not help cardiac recovery, and gradual activity rebuilds both fitness and confidence. Our guide to exercise after cardiac arrest covers this in more detail.

There is no universal timeline. When you can return to work depends on several factors: the physical and cognitive demands of your role, how your recovery is progressing, whether you have had an ICD fitted, and whether DVLA restrictions affect getting to work or doing the job itself.

People in sedentary or desk-based roles sometimes return within a few weeks, once the immediate physical recovery from the arrest and any procedure is underway. For physically demanding roles, the timeline is usually longer, and some adjustments may be needed. Fatigue and cognitive effects — including difficulties with concentration, memory, and processing — are common in the early months and can affect even those in office-based work.

Your cardiologist should be involved in any return-to-work decision. If your employer has an occupational health service, a referral is strongly recommended. They can advise on a phased return, reasonable adjustments, and any specific risks associated with your workplace. Our page on returning to work after cardiac arrest covers this in more detail, and benefits information is available if you are unable to work during your recovery.

Online peer support is valuable, and many members find it life-changing. But meeting in person adds something that a screen cannot. You see a face. You hear a voice. You sit opposite someone who truly gets it, without having to explain yourself, and something shifts.

Many members describe the first meet up they attended as a turning point in their recovery. The research on social support and recovery from serious illness consistently points in the same direction: in-person connection matters. Peer support from people with shared experience matters even more.

If you are on the fence, read what our members wrote about their experience of our October 2025 regional events in Together Through Recovery.

Completely normal, and very common. Walking into a room full of strangers takes courage at the best of times. After a cardiac arrest, when you may already be dealing with anxiety or a changed sense of who you are, it can feel like a significant step.

Most people who have attended their first SCA UK meet up describe the same thing: it was harder to get through the door than they expected, and far better on the other side of it than they had imagined. The moment someone else in the room says something you have never heard anyone say before, and you realise they understand exactly what you mean, is one of the more remarkable experiences recovery has to offer.

You can always come for an hour and see how you feel. No one will put you on the spot or expect anything of you. And if you want to ask questions or read reflections before committing, our blog post Together Through Recovery captures what attending felt like for those who came.

Category: Meet Ups and Events

Yes, and it is more common than most people realise. Partners, family members, and others who witnessed the arrest or performed CPR often experience their own trauma, anxiety, and adjustment difficulties. In some cases the distress of the people around a survivor is more acute, at least initially, than the survivor’s own. We use the term co-survivor to recognise this, because the people around a cardiac arrest are not simply bystanders. They live with the consequences too.

The same NHS and private support routes available to survivors are open to co-survivors. Your partner can speak to their own GP, self-refer to NHS Talking Therapies in England, or access private therapy. As a member of our community, co-survivors may also be eligible for the free private counselling sessions available through our SADS UK partnership.

We have a dedicated section on our site for co-survivors, and our community is full of partners and family members who understand exactly what your partner is going through. Encouraging them to connect with others who have been in the same position can make a significant difference.

Several types of support are available across the UK.

NHS support: Cardiac rehabilitation is available after a cardiac arrest and typically includes physical recovery, education, and psychological support. Ask your cardiology team or GP for a referral. Your GP can also refer you to NHS Talking Therapies for anxiety or depression, or you can self-refer in England without seeing your GP first.

SCA UK: Sudden Cardiac Arrest UK is a peer-led charity supporting survivors, co-survivors and bereaved families across the UK. We offer a large active community, a library of information resources, and access to free private counselling sessions for eligible members through our partnership with SADS UK. Joining is free. Join our community.

Private therapy: If NHS waiting times are too long, private counselling from a BACP-registered or UKCP-registered therapist can be quicker, though there is a cost. Our counselling page covers how to find a suitable therapist.

It depends entirely on why your cardiac arrest happened. For some survivors, the underlying cause is identified and successfully treated, which substantially reduces the risk of recurrence. For others, particularly those whose cardiac arrest arose from an ongoing arrhythmia or structural heart condition, some elevated risk remains. This is one of the reasons an ICD may be recommended.

Your cardiologist is the right person to discuss your individual risk with. They will have assessed the cause of your arrest and the condition of your heart, and they can give you a clearer picture than any general answer can. It is a reasonable and important question to ask directly.

Living with uncertainty about recurrence is one of the harder aspects of cardiac arrest survival, and the fear of it happening again is one of the most common concerns survivors raise. It does not mean the risk is high. Many survivors find that understanding their risk, even if it is not zero, is less frightening than not knowing. Peer support from others who have navigated the same uncertainty is something our community offers in abundance.

Category: Cardiac Arrest

For most people, life with an ICD is largely unchanged, with some practical adjustments. The ICD monitors your heart rhythm continuously and will deliver a shock if it detects a dangerous rhythm. Most of the time you will not be aware it is there.

There are a few areas to be aware of. Driving is restricted initially, and the rules depend on several factors including the type of rhythm that caused your arrest. Certain sources of strong electromagnetic fields can interfere with an ICD, though the risk in everyday life is low. Some sports, particularly contact sports, need review with your clinical team. Your cardiologist or cardiac nurse specialist will go through the specifics with you.

What many survivors find hardest is the psychological adjustment: knowing that a device is watching your heart, and wondering what it means if it activates. Many ICD recipients describe an initial period of anxiety that eases considerably with time. Our site has detailed information on living with an ICD, and our community includes thousands of ICD recipients, many of whom have been living with one for years and are happy to share their experience.

Yes, very much so. Anxiety, depression, and post-traumatic stress are all recognised clinical responses to life-threatening events, and cardiac arrest is about as life-threatening as it gets. These are not weaknesses or character flaws. They are your nervous system responding to something genuinely terrifying.

Anxiety is particularly common after cardiac arrest, often centring on fear of another arrest, heightened awareness of the heartbeat (sometimes called cardiac hypervigilance), or avoidance of activities that feel risky. Depression affects many survivors too, often arriving some weeks after the event, once the initial adrenaline of survival has worn off.

If feelings like these are persisting beyond a few weeks, are severe, or are affecting your daily life, speak to your GP. There are effective treatments, including CBT, EMDR, and medication. Peer support also helps many people enormously. Members of our community may also be eligible for free private counselling sessions through our partnership with SADS UK.

Most survivors find a new normal rather than returning to the old one. The event changes you, and there is no honest way around that. The question most people are really asking is: will life ever feel worth living again, will the fear ever ease, will I stop feeling like a stranger in my own body? The answer to all of those, for the vast majority of survivors, is yes.

It takes time. How much time varies enormously. Some survivors feel themselves again within months. Others take years. Many describe a gradual shift rather than a sudden moment, where they realise one day that they went several hours without thinking about the arrest, or did something they had been avoiding, or laughed without it feeling odd.

The things that seem to help most are peer support (talking to others who have been through it), appropriate professional help if anxiety or depression are significant, and resisting the urge to compare your recovery to someone else’s. You can read about the emotional journey in more detail on our roller coaster page, and connect with thousands of survivors at different stages in our community.

There is no single answer, and anyone who gives you a confident one is guessing. Physical recovery after a cardiac arrest is often longer than people expect. CPR can cause significant chest wall injuries (cracked or bruised ribs and a sore sternum are common), and the resulting pain and breathlessness can take weeks to months to resolve. Profound fatigue is also very common and frequently persists long after other physical symptoms have eased. If you have had an ICD fitted, or undergone other procedures, recovery from those adds further time. Returning to normal levels of activity typically takes several months, and cardiac rehabilitation is an important part of that process.

Emotional and psychological recovery is often slower, and less predictable. Anxiety, intrusive memories, low mood and fatigue are all common and can persist well beyond the point where you feel physically recovered. For some survivors, the emotional adjustment continues for years. That does not mean you are doing it wrong.

Progress is rarely linear. Many survivors describe a pattern of feeling better, then having a setback, then moving forward again. If the emotional side is not improving with time, or is getting worse, speaking to your GP is the right step. Effective support exists. Our counselling and talking therapies page covers the options available to you. You can also read more about emotional issues after cardiac arrest and connect with others in our community who are at different stages of the same journey.

For most survivors, yes, though “better” rarely means the fear disappears entirely. The more honest and useful word is subdued. The fear can be subdued to the point where it no longer controls your decisions, no longer dominates your days, and no longer prevents you from living the life you want to live.

What tends to help most is time, peer support, and appropriate psychological care if needed. Understanding that the anxiety is a normal response to an abnormal event, rather than evidence that something is still wrong, is itself a significant step for many survivors.

The fear may never fully leave. Many long-term survivors describe an ongoing awareness of their mortality that was not there before. But awareness is not the same as fear, and fear is not the same as it winning. Most survivors, given the right support, find that they adjust, and that life on the other side of a cardiac arrest can be rich, purposeful, and genuinely good.

SCA UK exists precisely for this. We are a peer-led survivorship community of over 4,000 cardiac arrest survivors and their families, with regional groups across the UK and an active online community where survivors share experiences, ask questions, and support one another.

Peer support after cardiac arrest has a strong evidence base. Talking to someone who has genuinely been through the same experience, who understands the fear, the hypervigilance, and the strange work of rebuilding trust in your body, is different from any other kind of support. It does not replace clinical care, but it complements it in ways that clinical care cannot.

It is very common, and it is important to say so clearly.

Research consistently shows that many cardiac arrest survivors live with lasting effects — whether physical, cognitive or psychological — even when their clinical results look reassuring. Feeling that something has changed, that you tire more easily, worry more, or simply cannot quite get back to who you were before, is a recognised part of survivorship. It does not mean something has been missed medically. It means recovery is complex.

Some of the effects of cardiac arrest are visible — a scar, a device, a medication. Others are invisible. Cognitive changes such as slower processing, difficulties with memory or concentration, and fatigue that does not match how you look from the outside are all commonly reported. So is a persistent sense of anxiety, hypervigilance about your own body, or a changed relationship with the future.

These experiences are not a sign of weakness or failure to recover. They are normal responses to an event in which your heart stopped.

If you are not feeling back to normal, it is worth raising this with your GP or cardiac team rather than waiting to see if it resolves. You deserve support that reflects the full complexity of what you have been through, not just a reassuring scan result.

Category: Psychological Support

Good follow-up care after cardiac arrest should be tailored to the individual, rather than relying on a standard set of tests that produce a single summary score.

For older survivors, good follow-up would include a careful assessment of physical functioning — the ability to move around, carry out self-care, manage daily activities and live independently. Identifying these difficulties early means support and adaptations can be put in place before problems become entrenched.

For younger survivors, good follow-up would include deliberate, compassionate attention to psychological wellbeing — anxiety screening, assessment for PTSD and depression, and support for returning to work and social life. These are not optional extras; they are core outcomes that matter as much as cardiac function.

For all survivors, good follow-up should treat quality of life as having several distinct dimensions — physical, psychological, cognitive and social — not as a single measure. It should continue beyond the first few months, since some effects of cardiac arrest emerge or persist over a longer period.

The RCUK Survivor Quality Standard, published in 2024, sets out a framework for exactly this kind of follow-up. If you are not receiving structured review that addresses your whole experience, it is worth asking your GP or cardiac team what is available to you.

Category: Psychological Support

The underlying findings are broadly relevant to UK survivors. The physical and psychological challenges of recovering from cardiac arrest are not specific to any country, and the core patterns are consistent with research from across Europe and beyond.

Older survivors everywhere face the risk of increasing physical limitations. Younger survivors everywhere can struggle with anxiety and psychological adjustment following a traumatic cardiac event. These are consequences of the biology of cardiac arrest and of what it means to face your own mortality at different stages of life, not features of any particular healthcare system.

The specific numbers in the Danish study may vary slightly in a UK setting, and differences in healthcare provision, rehabilitation access and follow-up models will shape how well survivors are supported. But the fundamental message — that recovery looks very different depending on age, and that a single overall measure is not sufficient — applies directly here.

The RCUK Survivor Quality Standard and international guidelines from the European Resuscitation Council, both of which are relevant to UK practice, reflect similar principles about the need for personalised, domain-specific follow-up care.

Category: Cardiac Arrest

Yes, based on current research and international guidelines, they should.

Mental health screening — including assessment for anxiety and depression — is recommended as part of post-cardiac arrest follow-up care by the National Institute for Health and Care Excellence (NICE) and the European Resuscitation Council. Psychological distress is common after cardiac arrest, affecting an estimated 15 to 30% of survivors, and can be just as disabling as physical limitations.

In practice, many follow-up appointments focus primarily or exclusively on cardiac function — the echocardiogram, the device check, the heart rhythm. While these are important, they tell your clinical team very little about how you are managing your anxiety, your sleep, your ability to return to work, or your fear of a recurrence.

If your appointments have not included a conversation about your mental health or psychological wellbeing, it is worth raising this yourself. You might say: “I’ve been struggling with anxiety since the arrest” or “I don’t feel like myself — is there support available?” Your GP, cardiologist or cardiac rehabilitation team can make referrals to psychological support services.

You do not have to wait until things reach crisis point. Raising concerns early leads to better outcomes.

Category: Cardiac Arrest

This is exactly the point that recent research has highlighted. When clinicians use a single overall score to measure how a survivor is doing, it can average out very different problems and make everyone appear roughly similar on paper.

In a large Danish study of over 2,500 survivors, the overall quality-of-life scores varied little between age groups. On a summary measure, older and younger survivors looked broadly comparable. But when researchers examined individual areas — mobility, self-care, usual activities, anxiety and depression — clear and significant differences between age groups appeared.

As the study’s commentators put it, summary measures can make meaningfully different survivorship burdens appear deceptively similar. A 67-year-old with limited mobility and a 32-year-old with persistent anxiety may score identically on a composite scale. But they are not having the same experience of survival.

This matters practically. If your doctor sees a reassuring overall score and moves on, real difficulties in specific areas can go unaddressed. If you feel something is wrong but have been told your scores look fine, you are right to push for a more detailed conversation about how you are actually living day to day.

Category: Life After Cardiac Arrest

After a cardiac arrest, both the body and mind go through a significant recovery process. The difference age makes comes down to what each group is most vulnerable to at that stage of life.

For older survivors, a cardiac arrest can accelerate or worsen physical decline that was already beginning. Mobility, self-care and the ability to carry out daily activities can all become noticeably harder. These changes may seem gradual, and it is not always easy to connect them clearly to the arrest, particularly when overall clinical scores look reassuring.

For younger survivors, the psychological impact tends to dominate. Being young and otherwise healthy, then experiencing a sudden, life-threatening event, can trigger intense anxiety and a lasting fear that it will happen again. There is also the disruption to work, family life and long-term plans that older survivors may be less reliant on in the same way.

A major Danish study of 2,552 survivors found that older survivors (particularly those over 75) reported significantly higher rates of physical difficulty, while those under 35 showed anxiety levels of nearly 30%. These are genuinely different experiences of the same event, shaped by age and life stage — and they call for different types of support.

Most people who survive a cardiac arrest can return to their previous level of functioning, though the timeline varies and recovery often continues for a year or more. Cognitive and psychological recovery commonly takes longer than physical recovery.

All survivors need ongoing follow-up care with a cardiologist or electrophysiologist. This typically includes regular device checks if an ICD has been fitted, review of any medication, and assessment of how recovery is progressing. Cardiac rehabilitation is also recommended and has good evidence for improving outcomes.
