Comparison of cardiac function between left bundle branch pacing and right ventricular outflow tract septal pacing in the short-term: A registered controlled clinical trial

摘要

Background: The novel method of left bundle branch pacing (LBBP) has been reported to produce a narrower QRS duration and lower pacing threshold than right ventricular outflow tract septal pacing (RVOP). However, whether LBBP is superior to traditional RVOP in improving cardiac function still lacks sufficient evidence.
