Ventricular Pace Suppression Study

Ventricular Pace Suppression Study With the EVIA/ENTOVIS DR-T/DR Pacemaker

Investigation of the efficacy and safety of the Ventricular Pace Suppression (VpS) algorithm.

The aim of this study is to investigate the percentage of reduction of ventricular pacing using the VpS feature of the EVIA/ENTOVIS pacemaker in a controlled clinical investigation.

• DDD(R)-ADI(R)-Mode (VpS Algorithm) applicability

Exclusion Criteria:

• Permanent AV block III°
• Permanent Atrial Fibrillation/ Flutter
• Require mode other than DDD(R)-ADI(R) or DDD(R)
• Have a life expectancy of less than six months
• Expected to receive heart surgery within six months
• Enrolled in another cardiac investigation
