Study Overview
Brief Summary
Typically pacemaker electrode has been attached to the right ventricular apex. This method lead to Non-physiological Ventricular contraction. It has been reported to cause by ventricular dysfunction. In conclusion, this study demonstrate that impact of right ventricular pacing determined by electrocardiography was planned.
Detailed Description
Patients who has Atrioventricular block scheduled for artificial pacemaker Randomized select 1:1 apex beats and ventricular septal beat.
