心绞痛是心肌氧的供需暂时失衡,而致心肌乏氧的一组临床综合征。心电图上ST段的偏移是临床上判定心肌缺血的重要指标之一。但是,心绞痛发作时ST段抬高和ST段下降的临床意义尚不十分清楚。就此作者进行了心绞痛发作ST段抬高和下降的冠状动脉造影的研究。研究方法本组在34例患者28次ST段抬高和13次ST段下降共41次心绞痛发作时进行了冠状动脉造影。23例稳定型心绞痛伴有ST段抬高,其中
Angina pectoris is a temporary imbalance of supply and demand of myocardial oxygen, which results in a group of clinical syndromes of myocardial hypoxia. ST segment ECG offset one of the important indicators of myocardial ischemia. However, the clinical significance of ST-segment elevation and ST-segment decline during angina pectoris is not yet clear. In this connection, the authors studied angiographic ST segment elevation and decreased coronary angiography. Methods of study This group of patients in 34 patients with 28 ST-segment elevation and 13 ST-segment decline in 41 episodes of angina underwent coronary angiography. Twenty-three patients with stable angina accompanied with ST-segment elevation
