Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Although emerging evidence demonstrated that left bundle branch pacing (LBBP) is a promising alternative for patients with either a bradycardia or a heart failure pacing indication. However, a direct comparison of the safety, efficacy and LV systolic synchrony between LBBP and RVP regimens was rare. In this study, the investigators aim to conduct a comparison of the safety and effectiveness performance between these two pacing methods for patients with atrioventricular block (AVB). The investigators focused on AVB patients undergoing permanent pacemaker implantations from the 1st of January 2018 to the 18th of November 2021 at West China Hospital.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Right ventricular pacing (RVP) is the standard treatment for patients with continuous ventricular pacing needs. However, clinical studies have shown that RVP can cause electrical and mechanical dyssynchrony of the left ventricle and increase the risks of cardiac insufficiency, atrial fibrillation (AF) and death. Although emerging evidence demonstrated that left bundle branch pacing (LBBP) is a promising alternative for patients with either a bradycardia or a heart failure pacing indication. However, a direct comparison of the safety, efficacy and LV systolic synchrony between LBBP and RVP regimens was rare. In this study, the investigators aim to conduct a comparison of the safety and effectiveness performance between these two pacing methods for patients with atrioventricular block (AVB). The investigators focused on AVB patients undergoing permanent pacemaker implantations from the 1st of January 2018 to the 18th of November 2021 at West China Hospital.

Intervention Type PROCEDURE

After recording the His potential, the 3830-69 lead (Medtronic Inc., Minneapolis, MN USA) was sent 1-2 cm forward and downward to find the insertion point of the right side of intra-ventricular septum combined with the pre-rotation impedance and ECG changes. Ultimately, the tip was perpendicularly straightforward posited against the septum to the left septal side .
