title: Death due to an implantable cardioverter defibrillator.
abstract: Inappropriate therapy due to noise oversensing caused a true ventricular fibrillation (VF) and death of a patient. A 49-year-old patient with a history of dilated cardiomyopathy received a double-chamber implantable cardioverter defibrillator (ICD) in 1991 for a sustained inducible ventricular tachycardia (VT). One appropriate shock delivered in 1994 terminated an episode of VT. The generator was replaced in 1995 and in 2000, and was connected to the initial leads. Three months after the second replacement, the patient received six consecutive shocks related to detection of noise interpreted as VF. Unfortunately, the sixth shock triggered a true VF, which was not treated due to end of the therapeutic sequence, and the patient died. The causes of the dysfunction are discussed.
