NCT05600699

Brief Summary

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.

Study Population

From April 2018 to Dec 2019, consecutive patients who were predicted to require a high percentage of ventricular pacing in our center were enrolled in this study. Main indications for the enrolment of patients are atrioventricular block and heart failure (HF) combined with complete left bundle branch block (LBBB). All patients were accorded with indications for pacing therapy of 2013 European Society of Cardiology guidelines on cardiac pacing. The study conforms to the guiding principles of the Declaration of Helsinki and was approved by Ethics Committee of the Linyi People's Hospital. All patients signed the informed consent.

You may qualify if:

  • Patients who were predicted to require a high percentage of ventricular pacing in our center were enrolled in this study

You may not qualify if:

  • Low rate of pacing, and loss to follow-up
