【摘要】 目的 通过冠状动脉造影观察变异性心绞痛冠脉病变程度与动态心电图一过性ST段抬高的关系。方法 对46例动态心电图有一过性ST段抬高患者行冠状动脉造影检查。结果 46例变异性心绞通患者中，冠脉造影检查示冠状动脉伴有意义狭窄者共43例，其中狭窄>70%者达33例(占72%);>70%狭窄者:ST段抬高在>0.2mV，≤0.2mV者中分别占86%(30/35)，27%(3/11)，二者相比差异无显著性(P<0.05);在ST段抬高最长持续叶间<3min者，≥3min者中分别占44%(8/18)，89%(25/28)，二者相比差异无显著性(P<0.05)。结论 变异性心绞痛更易于在有病变的冠状动脉上发生，当冠脉痉挛发生时，ST抬高的时间、高度与冠脉狭窄的程度呈正相关。

    【Abstract】 Objective To study the relation of coronary stenosis and temporary ST elevation in dynamic electroˉcardiography in variable angina(VA).Methods The data of DCG and coronary artery angiography(CAG)in46cases were studied with paroxysmal ST elevation in dynamic electrocardiography were studied.Results There were43patients who had significant stenosis of coronary artery through CAG in46patients.There were33cases stenosis of>75%;The percent of ST elevation≤0.2mV ......
