The Automated Implantable Cardiac Defibrillator

A patient with cardiac sarcoidosis proved by biopsy specimen and no history of sudden death or clinical sustained ventricular tachycardia prophylactically received an implantable cardioverter defibrillator (ICD) that later reversed an episode of near syncope. The patient was supported with the ICD until heart transplantation. The physiology and treatment of arrhythmias associated with cardiac sarcoidosis is described. Consideration for use of the ICD in asymptomatic patients and as bridge therapy until heart transplantation is discussed.
