摘　　要：目的:探讨右心室高位和中位室间隔起搏对心肌跨膜离散度指标的影响。方法:54例Ⅲ度房室传导阻滞患者按照随机数字表法分为右心室高位间隔部组(高位组)和中位间隔部组(中位组),比较两组术前、后QRS宽度、T波峰末间期(Tp-e)、校正T波峰末间期(Tp-ec)、Tp-e/QT值。结果:右心室高位和中位室间隔起搏组术后较术前QRS宽度、Tp-e、Tp-ec、Tp-e/QT值均增加,中位较高位室间隔组术后QRS宽度、Tp-e、Tp-ec、Tp-e/QT值要小,但两组比较差异均无统计学意义(P>0.05)。结论:右心室高位和中位室间隔起搏均会导致心肌跨膜离散度指标延长,但两组无显著差异。Objective：To observe the effect of the high and the mid right ventricular septal pacing on the transmural dispersion of repolarization. Method：54 patients with complete atrioventricular block were randomly divided into high right ventricular septal group and mid right ventricular septal group.The QRS wave duration,Tp-e interval,Tp-ec interval and Tp-e/QT ratio before and after operation were measured and compared.Result：The QRS wave duration,Tp-e interval,Tp-ec interval and Tp-e/QT ratio were all prolonged in the two groups after operation.These parameters were shorter in the mid right ventricular septal group,but there were no significant difference between two groups（P〉0.05）.Conclusion：The high and the mid right ventricular septal pacing groups both could prolong the parameters of transmural dispersion of repolarization,but no significant difference between the two groups was observed.
