Primary Outcome Measures

Name	Time	Method
Number of patients with successful defibrillation at 35 Joules.	24 hours	After manual induction of ventricular fibrillation, a 35 Joules will be delivered with the implanted defibrillator.

Secondary Outcome Measures

Name	Time	Method
Time from ventricular fibrillation induction to defibrillation shock.	24 hours	After manual induction of ventricular fibrillation, the duration of appropriate ventricular sensing will be measured until the 35 Joules shock is delivered.
Number of appropriate and inappropriate arrhythmic episodes.	6 months	The occurrence of appropriately or inappropriately detected episodes with a high ventricular rate ≥170 beats-per-minute will be recorded.
