Aktiv komparator: Fusion Pacing OFF
Subjects initially randomized to the Fusion Pacing OFF Arm will receive the Fusion Pacing software download at the implant visit, but the Fusion Pacing software will be programmed OFF.
At 4 months subjects in this arm will crossover to the Fusion Pacing ON Arm.

Market approved InSync Sentry™ model 7298, dual chamber Implantable Cardioverter Defibrillator (ICD) with Cardiac Resynchronization Therapy (CRT) including sequential biventricular pacing and OptiVol® fluid monitoring or market approved InSync Maximo™ model 7304 dual chamber ICD with CRT including sequential biventricular pacing.
