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.
