Figure 2 Morbidity Index for the PREPARE Study Patients Versus the Control Cohort

The PREPARE study patients had fewer morbidity index events (primary end point) as compared with the control cohort. Both appropriate and inappropriate shocks were substantially reduced in the PREPARE study programmed patients. There were relatively few syncopal events that contributed to the primary end point. SVT = supraventricular tachycardia or other nonventricular tachycardia or ventricular fibrillation event; VF = ventricular fibrillation; VT = ventricular tachycardia.
