摘　　要：目的:探究右心室不同部位起搏对心电图心功能的影响。方法:收治Ⅱ度Ⅱ型或Ⅲ度房室传导阻滞行永久性起搏器治疗患者100例,分为两组。对照组采用心尖部(RVA)起搏,试验组采用右心室间隔部(RVS)起搏,比较两组心功能。结果:试验组治疗后1个月的LVEF水平明显高于对照组,试验组LVPWT、LVEDD水平低于对照组,差异具有统计学意义(P<0.05)。结论:右心室间隔部(RVS)起搏治疗房室传导阻滞对心功能的影响较小,更有利于保持心肌电活动和机械收缩的同步性。Objective:To explore the effects of pace-making in different parts of right ventricular on cardiac function.Methods:100 cases of patients with degree Ⅱ type Ⅱ or degree Ⅲ atrioventricular block treated with permanent pace-making were divided into two groups.The control group was given right ventricular apex pace-making,and the experiment group was given right ventricular septum pace-making.The cardiac function of the two groups was compared.Results:The LVEF levels of the experiment group at 1 months after treatment were significantly higher than those in the control group.The levels of LVEDD and LVPWT in the experiment group were lower than those in the control group.The differences were statistically significant (P<0.05).Conclusion:Right ventricular septum (RVS) pace-making in the treatment of atrioventricular block had less effect on cardiac function,which was more conducive to maintain the synchronization of cardiac electrical activity and mechanical contraction.
