METHODS: Rat model of acute myocardial ischemia induced by pituitrin was used in this study, and the lift of st segment in ECG was used as the index of myocardial ischemia.
方法：应用垂体后叶素致大鼠急性心肌缺血模型，以心电图上ST段的抬高作为心肌缺血的指标。
Methods: 1. According to the changes of ST segment in ECG and coronary angiography, 87 cases were divided into three groups: coronary heart disease(C) group and hypertension (H) group.
方法：1、选择87例因体表心电图ST段异常改变的住院患者，经冠状动脉造影后分为单纯冠心病组及高血压组。
Results The frequencies of ECG ST T abnormalities were higher in Guangzhou, rural and women than those in Beijing, urban and men respectively. T wave abnormalities were much more than ST segment.
结果STT异常的发现率在广州地区、农村人群、女性人群较高，北京地区、城市人群、男性人群较低，T波异常明显多于ST段异常。
