The Optimal Anti-tachycardia Therapy in ICD Patients Without Pacing Indications study [OPTION; NCT00729703] was designed to test the hypothesis that DC ICD therapy with specific device-based algorithms would reduce the rate of inappropriate shocks without affecting morbidity and mortality by ventricular pacing.
