摘　　要：目的:探讨冠心病心肌缺血与室性心动过速和室性心动过速与QT离散度、JT离散度的关系。方法:选择符合国际心脏病学会及WHO诊断标准的病人65例,其中合并室性心动过速者30例（VT组）,无合并室性心动过速者35例（NVT组）;同期经各项检查未发现心脏病者35例（对照组）,予以动态心电图、常规心电图检查,并对所得数据进行统计学处理。结果:室性心动过速组、无室性心动过速组两组的QT离散度、JT离散度,心肌缺血情况,室性早搏的发生率有显著差异,分别为P<0.01,<0.01,<0.05,<0.05。结论:冠心病心肌缺血与室性心动过速有一定的关系,室性心律失常的严重程度与QT离散度有关。Objective: To explore the correlation between myocardial ischemia and QT dispersion (QTd) and correlation between QTd and ventricular arrhythmia. Methods: Electrocardiogram and dynamic electrocardiogram estimating were executed in 65 patients with coronary artery disease (CHD) and 35 healthy controls. CHD patients were divided to ventricular tachycardia group (VT group> 30 cases) and no ventricular tachycardia group (NVT group, 35 cases). Results: Degree of QTd、JTd、myocardial ischemia in VT group increased than those of NVT group (P<0. 01, < 0.01, <0.05). Ventricular premature beat also increased in VT group than that of NVT group (P<0.05). Conclusion: There are correlation between myocardial ischemia and QT dispersion (QTd) and correlation between QTd and ventricular arrhythmia.
