摘　　要：目的为了比较右心室流出道室间隔部起搏与右心室心尖部起搏两者对患者心功能等指标的影响。方法对我院19例需要安置起搏器的患者随机分为右心室流出道室间隔部起搏与右心室心尖部起搏两组患者,观察术后3个月两组患者在心功能、心电图、及心脏彩超等方面的变化。结果室间隔组治疗后心功能分级较心尖组略有好转,左室射血分数(EF)值较心尖组略有改善,但两者均没有达到统计学意义;QRS波群时限心尖组患者较室间隔组明显延长,达到统计学意义。结论室间隔流出道起搏较心尖部起搏更加符合人体的生理性特点,更不容易导致左右心室收缩的不同步,对患者的心功能影响较小。Objective To compare the heart function of pacing in right ventricular septum with in right ventricular apex. Methods 19 patients who needed pacemaker were randomly divided into pacing in right ventricular septum group and pacing in ringht ventricular apex group, to observe the difference of heart function, electrocardiogram and echocardiography between the two groups after 3 months. Results Heart function and left ventricular ejection fraction were slightly better in fight ventricular septum group, but there were on significant differences. QRS duration was obviously delayed in fight ventficular apex group, and there was significant difference. Conclusion Pacing in fight ventricular septum is in conformity with the body＇s physiological characteris- tics, because it less lead to ventricular asynchronism and heart dysfunction.
