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.
