implantable cardioverter-defibrillators (ICDs)

An implantable cardioverter-defibrillator (ICD) is a small device placed under the skin around the chest area that monitors your heart rhythm continuously. If it detects a dangerously fast or irregular heartbeat (arrhythmia), it can deliver electrical pulses or shocks to restore a normal rhythm. ICDs are primarily used for individuals at risk of sudden cardiac arrest due to serious arrhythmias. They work automatically, providing life-saving therapy without needing to be operated manually. The device helps keep the heart functioning properly and reduces the risk of sudden death from cardiac problems.
