Impact of Right Ventricular Pacing Determined by Electrocardiography

Not Applicable

Completed

• Conditions: Atrioventricular Block
• Interventions: Procedure: Septal pacing; Procedure: Apex pacing

• Registration Number: NCT01922518
• Lead Sponsor: Yong Seog Oh

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.
