An overnight stay in hospital is typical after an ICD implant, though some patients go home the same day. Most people are back to light everyday activities within two to three days of the procedure.
It is common to have soreness and tenderness around the wound site for several days, and bruising is normal. The wound usually heals within one to two weeks. For the first few weeks, your cardiologist will advise you to avoid lifting your arm above shoulder height on the side of the implant and to hold off on strenuous activity. This allows the leads and the wound to settle properly.
Your device clinic will give you specific guidance on activity restrictions for your situation. If you are concerned about anything during recovery, contact your device clinic or call NHS 111. Our page on living with an ICD covers what to expect in more detail, and members of our community who have been through the procedure are usually happy to share their experience.
