Implantable Cardioverter Defibrillators (ICD)

Implantable cardioverter defibrillators (ICD) are small electronic devices placed in people who are at risk of sudden cardiac death due to ventricular tachycardia, ventricular fibrillation, a weakened or enlarged heart, congenital heart disease or a genetic health condition. Implanted in the chest, the ICD detects any life-threatening rapid heartbeat, or arrhythmia, and sends an electrical shock to the heart to bring the rhythm back to normal.
