Atrioventricular Block

Keywords

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.

Interventions

PROCEDURESeptal pacing

Put RV pacing lead around the right ventricular septum and is adjusted with normal pacing axis

PROCEDUREApex pacing

Put RV lead around the apex
