Left Bundle Branch Area Pacing in AVB Patients

This study is intended to be included in Fuwai hospital for admission to the atrioventricular block, with permanent pacemaker implant indications recommended by current guidelines. Patients were assessed for preoperative electrocardiogram, quality of life scores, cardiac function, and left and right ventricular synchrony. Patients were followed up by regular outpatients. The electrocardiogram, quality of life score, echocardiographic function, left and right ventricular synchrony, pacing parameters and pacing ratio were evaluated immediately after surgery, 3 months, 6 months, and 12 months after surgery. At the same time, the left bundle branch area pacing success rate, complications during intraoperative and postoperative follow-up were recorded.
