Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Chronic right ventricular apical pacing has been associated with negative hemodynamic effects. Clinical outcome of right ventricular pacing can be influenced by multiple factors. An important factor seems to be optimal lead positioning. Data regarding left ventricular function impaired by lead positioning is insufficient. The aim of the present study therefore is to compare right ventricular apical pacing (RVAP) with right ventricular septal pacing (RVSP). Outcome measurements are echocardiographic features, magnetic resonance imaging and clinical outcome.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

RVAP lead

Pacemaker lead implantation:

Pacemaker leads will be placed in specific predefined RA and RV sites according to randomization. In this arm pacemaker leads will be placed in the RV apex. The successful lead positioning at its target location will be verified by surface ECG and by fluoroscopy.

Group Type EXPERIMENTAL

RVAP

Intervention Type OTHER

In this arm pacemaker leads will be placed in the RV apex.

RVSP arm

Pacemaker lead implantation:

Pacemaker leads will be placed in specific predefined RA and RV sites according to randomization. In this arm pacemaker leads will be placed in the RV septum. The successful lead positioning at its target location will be verified by surface ECG and by fluoroscopy.

Group Type EXPERIMENTAL

RVSP

Intervention Type OTHER

In this arm pacemaker leads will be placed in the RV septum.
