摘　　要：目的:探讨静息心电图持续性ST-T改变与冠心病的关系。方法:对86例持续性ST-T改变患者行选择性冠状动脉造影术和活动平板运动试验,并对结果进行分析。结果:86例患者中,17例(19.8%)造影发现有冠状动脉狭窄,其中活动平板运动试验阳性者15例,占冠状动脉狭窄患者的88.2%(15/17)。结论:静息心电图持续性ST-T改变不是冠心病的特异性改变,绝大多数并非由冠状动脉狭窄引起,应努力寻找其他原因。Objective：To investigate the relationship between resting sustained electrocardiogram （ECG） ST-T changes and coronary heart disease. Method： Eighty-six cases with sustained ECG ST-T changes were diagnosed by selective coronary angiography and treadmill exercise ECG-test, then we analyzed the clinical data. Result： Coronary stenosis was detected in 17 eases （19.8 % ）. And the treadmill exercise test was positive in 15 cases, accounting for 88.2 % （15/17） of the patients with coronary stenosis. Conclusion：The resting sustained ECG ST-T changes may not be the special change of coronary heart disease, most of them do not caused by coronary stenosis, and we should try to find other underlying reasons.
