Evaluation of electrophysiological characteristics and ventricular synchrony: An intrapatient-controlled study during His-Purkinje conduction system pacing versus right ventricular pacing.

ABSTRACT:

Objectives to background

To compare electromechanical ventricular synchrony when pacing from different sites, including right ventricular apex pacing (RVAP), right ventricular septum pacing (RVSP), His bundle pacing (HBP), left bundle branch pacing (LBBP), and RVSP during unipolar pacing from the ring electrode of LBBP lead (RVSP_ring ) in each patient and evaluate the correlations between electrophysiological characteristics and ventricular synchrony.

Methods

Twenty patients with complete atrioventricular block indicated for dual-chamber pacemaker implantation were included in the study. Unipolar pacing at different sites, including RVAP, RVSP, HBP, LBBP, and RVSP_ring , was successively performed in each patient. The pacing characteristics and echocardi
