Official title:
Left Bundle Branch Pacing (LBBP) for the Treatment of Cardiac Dysfunction With Safety and Efficacy Study in Patients With Atrioventricular Block
This study periodically assessed patients' cardiac function and prognosis by cardiac ultrasound, NYHA cardiac function class, 6-minute walk distance, quality of life score (QoL), and clinical events at follow-up, with the aim of assessing whether LBBP is no less effective than CRT in patients with left ventricular ejection fraction (LVEF) <50% and estimated percentage of ventricular pacing >40% of cardiac dysfunction.
