Atrioventricular Block Clinical Trial
Official title:
Long-term Efficacy and Safety Research of Left Bundle Branch Pacing
Patients with successful left bundle branch pacing in our center were included in this study from April 2018 to December 2019. Baseline data was collected, and pacing parameters, ECG and echocardiographic results were analyzed during 3 years follow-up. According to whether or not a potential was recorded and the specific potential characteristics at implantation, the patients were divided into 3 groups: left bundle branch potential group; Purkinje potential group; and no-potential group. During the 3 years follow-up, the investigators collected the ECG、UCG and pacemaker parameters to analyze.
A total of 136 patients with a high percentage of ventricular pacing and successful left bundle branch pacing were included in this study from April 2018 to December 2019. Baseline data was collected, and pacing parameters, ECG and echocardiographic results were analyzed during 3 years follow-up. According to whether or not a potential was recorded and the specific potential characteristics at implantation, the patients were divided into 3 groups: left bundle branch potential group (L group) 31.6%; Purkinje potential group (P group) 10.3%; and no-potential group (N group) 58.1%. During the 3 years follow-up, the investigators collected the ECG、UCG and pacemaker parameters to analyze. ;
