What is an implantable cardiac defibrillator? An implantable cardiac defibrillator (ICD, or implantable cardioverter defibrillator) is an internal shocking device that provides immediate therapy to a life-threatening arrhythmia (heart beating too quickly) via a jolt of electricity. It can also act as a pacemaker if the heart is beating too slow.
Defibrillation is a treatment for life-threatening cardiac dysrhythmias, specifically ventricular fibrillation (VF) and non-perfusing ventricular tachycardia (VT). A defibrillator delivers a dose of electric current (often called a countershock) to the heart. This depolarizes a large amount of the heart muscle, ending the dysrhythmia. Subsequently, the body's natural pacemaker in the sinoatrial node of the heart is able to re-establish normal sinus rhythm.
