Detailed Description:

AV-Block of higher degree is the primary indication for pacing therapy for about 20% of pacemaker patients. Pacing systems with only ventricular stimulation (VVI and VDD) have a fraction of about 40% of all pacemakers in Germany. About 50% of the implanted pacemakers in Germany are dual-chamber pacemakers and one half of them is used for treatment of AV blocks.

A lot of studies proved in the past that the pacing site influenced the development of hemodynamics, heart failure (HF) and atrial fibrillation (AF). Unfortunately, the results are not commonly applicable or statistically assured. Due to this, further examinations are required in order to get explicit statements regarding application of alternative, nonapical ventricular lead positioning.

Pilotphase It shall be determined whether a randomized positioning of ventricular leads at 2 defined positions (either Group A: Positioning at right ventricular apex or Group B:. Positioning at right ventricular high septum) is feasible. Included patients will already by examined and followed according to protocol. After having proved feasibility of randomized positioning, the data of these patients shall be used for evaluation of the V-PASS study.
Study Phase It shall be evaluated how far 2 defined different ventricular lead positions for permanent pacemaker therapy can influence the combined study endpoint mortality and clinically relevant symptoms of heart failure. Further more the development of hemodynamics and the incidence of atrial fibrillation shall be studied.
