摘　　要：83例心绞痛患者经24小时动态心电图监测到528次缺血性ST段下移,分析结果表明:1.在心绞痛患者缺血性ST段下移中,无症状性心肌缺血占75％,发生次数是有症状的3倍;2.缺血性ST段下移,85％与活动有关;3.缺血性ST段下移有明显的昼夜分布规律,上午6—10时为发作高峰,占全天总次数32％。提示在冠心病治疗中应重视包括无症状性心肌缺血在内的总缺血负荷,并结合缺血的昼夜分布规律调整给药时间。The data of 528 episodes of ischemic ST segment depression in 83 patients with angina pectoris were studied by 24 hour ambulatory electrocardiogram. The results showed that: 1. The silent myocardial ischemia accounted for 75% of total ischemic ST segment depression with angina pectoris patients. It is of three times as many as symptomatic myocardial ischemia. 2. The 85% of ischemic ST segment depression was concerned with activities. 3. There was a circadian variation of ischemic ST segment depression. The frequency of change peaked at 6-10 Am. It accounted for 32% of all the day. It suggested that the total ischemic burden, including silent myocardial ischemia, should be paid much attention to the treatment of coronary artery disease. Meanwhile, we should adjust time of taking midicine according to day and night regularity of ischemic attack.
