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.
