Conference paper


Multiple reports from different institutions around the world have definitively demonstrated the efficacy of implantable cardioverter defibrillator (ICD) in the treatment of malignant ventricular tachyarrhythmias and in the prevention of sudden cardiac death. Despite efforts to reduce defibrillator size and defibrillation threshold while continuing to provide more sophisticated tiered therapy, inappropriate ICD discharges remain a relatively frequent clinical problem; in fact, it has been reported that about one-third of all shocks are delivered for reasons other than ventricular tachyarrhythmias. Frequent ICD shocks can cause pain and may impair ventricular function and quality-of-life of patients with an ICD. Repetitive activations may also determine early battery depeletion or finally be proarrhythmic (1) and even fatal (2).
