implantable cardioverter-defibrillator

An implantable cardioverter-defibrillator (ICD) is a small device placed under the skin, typically near the chest, to monitor and manage irregular heartbeats. If it detects a dangerous fast or abnormal heartbeat, it sends electrical shocks to restore normal rhythm. The ICD continuously checks the heart’s activity and can also record heart data for doctors. It is used in people at risk of sudden cardiac arrest due to serious arrhythmias, helping to prevent life-threatening episodes and improve overall heart health.
