Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Number of patients with successful defibrillation at 35 Joules.	After manual induction of ventricular fibrillation, a 35 Joules will be delivered with the implanted defibrillator.	24 hours
Secondary	Time from ventricular fibrillation induction to defibrillation shock.	After manual induction of ventricular fibrillation, the duration of appropriate ventricular sensing will be measured until the 35 Joules shock is delivered.	24 hours
Secondary	Number of appropriate and inappropriate arrhythmic episodes.	The occurrence of appropriately or inappropriately detected episodes with a high ventricular rate =170 beats-per-minute will be recorded.	6 months
