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.
Implantable cardioverter defibrillators are powered by batteries. The variety used has been chosen because of its long service period and the very predictable way in which its power is gradually used. If an ICD delivers a great many shocks, it will wear out sooner than one that seldom provides therapy.
