Image Location and Performance of Left Bundle Branch Pacing

Cardiac Pacing Clinical Trial

Official title: Image Location and Performance of Left Bundle Branch Pacing

Status Completed

Clinical Trial Summary

This is a prospective, multi-site, non-randomized, data collection study. The purpose of this study is to investigate the correlation between pacing sites and ECG morphology or pacing parameters during left bundle branch pacing (LBBP) and perform the use condition analysis to assess the long-term performance of pacing lead during LBBP.

Clinical Trial Description

His bundle pacing (HBP) is a physiological pacing, but also has some limitations, including high and unstable pacing threshold in 5-10% patients, low R-wave amplitude causing inappropriate pacing management, damage to the His bundle during implantation. On the other hand, left bundle branch pacing (LBBP), achieved via trans-ventricular septal approach with the pacing lead tip at the left side of the ventricular septum, has recently initiated and been widely practiced in China because of easy implantation, relatively narrow paced QRS duration, low and stable pacing threshold, high R wave amplitude, and the LBBB correction by a low pacing output.

As LBBP is in the early phase of clinical practice in China, in order to better conduct LBBP implantation and understand mechanisms of LBBP therapy, physicians often do imaging assessment of the pacing lead in patients implanted with LBBP based on clinical necessity.

Additionally, there is no report of mid/long-term correlation between lead location and ventricular electrical activity, nor mid/long-term pacing lead performance assessment during LBBP. ;
