Implantable Cardioverter-Defibrillators

Abstract

An implantable cardioverter defibrillator (ICD) is an active implantable medical device primarily used to deliver a high-energy electric shock to the heart via intracardial leads. The electric shock causes concurrent depolarization of all cell membranes in myocardial volume followed by an absolute refractory period. As a result, a tachycardia impulse spreading in the myocardium is interrupted. This implantable device also works as a pacemaker and applies antitachycardia pacing (ATP) to terminate ventricular tachycardia (VT) when high-energy shocks are not required.
