NCT01039467

Brief Summary

The COMPARE-Adapta study is a randomized, multi-center, prospective study conducted in China. The purpose of the study is to compare the ability of Search AV™+ and Managed Ventricular Pacing® (MVP®) to reduce ventricular pacing in dual chamber pacemaker-indicated patients. The COMPARE-Adapta study will also observe atrial fibrillation (AF) burden as demonstrated by Cardiac Compass® and the clinical profile Adapta® pacemaker patients.
