Abstract：Objective To compare the effects of His-bundle pacing (HBP) and right ventricular apical pacing (RVAP) in keeping right ventricular structure and systolic function. Methods The patients (n=39) undergone implantation of permanent pacemaker due to atrioventricular block (AVB) were chosen from the Department of Cardiology in the First Affiliated Hospital of Zhengzhou University and the Department of Cardiology in People's Hospital of Zhengzhou University from Mar. 2012 to Jan. 2015. Among all patients, 15 received HBP (HBP group) and 18 received RVAP (RVAP group). The patients were followed up and observed for 24 months, and changes of NYHA grading, left ventricular ejection fraction (LVEF) and left ventricular end-diastolic inner diameter (LVEDd) were compared. Results NYHA grading had no significant changes before and after implantation in HBP group (P>0.05), and NYHA grade was decreased from 1.4 before implantation to 2.5 after implantation in RVAP group (1.4 ±0.7 vs. 2.5±0.9, P<0.001). LVEF and LVEDd had no significant changes before and after implantation in HBP group (P>0.05), and LVEF decreased significantly [(58.3±6.3)% vs. (50.8±7.5)%, P=0.002] and LVEDd increased significantly [(43.1±4.6) mm vs. (53.3±7.9) mm, P<0.001] in RVAP group after implantation. Conclusion Compared with traditional RVAP, HBP has advantages in keeping cardiac systolic function and LVEDd.
