ICD (Implantable Cardioverter-Defibrillator)

An Implantable Cardioverter-Defibrillator (ICD) is a small device placed under the skin of the chest to monitor heart rhythms. If it detects dangerous arrhythmias—abnormal, rapid, or irregular heartbeats—the ICD delivers electrical shocks to restore a normal heartbeat, helping prevent sudden cardiac arrest. It acts as a safety device for individuals at risk of life-threatening arrhythmias, providing continuous heart rhythm surveillance and intervention without requiring external action. The ICD's goal is to protect and prolong life by promptly treating abnormal heart rhythms before they cause serious health events.
