摘　　要：本文对103例冠心病患者其中68例无症状心肌缺血进行24小时动态心电图分析,监测结果,陈旧性心肌梗塞和冠心病心绞痛两组无症状ST段压低均高于有症状(P<0.05),但两组之间有症状与无症状发生率无显著差异。68例无症状心肌缺血中有64例ST段压低均发生于日常活动和卧床休息时。发作时间以6～12点最多,缺血严重程度及时限与症状无关。The results of 24 hour ambulatory monitoring electrocardiography in 103 CHDpatients 68 of whom had silent myocardial ischemia were analysed, They were clini-cally divided into two groups: cases with previous myocardial infarction and caseswith angina. The incidence of silent myocardial ischemia was more frequent thanthat of symptomatic myocardial ischemia in both grouns. However, the frequency ofsilent myocardial ischemia and symptomatic myocardial ischemia between two groupsshowed no evident differences (P>0.05). Depressed ST-segments were found duringdaily activities and rest in 64 out of 68 patients with silent myocardial ischemia.The highest rate of ischemia fits was in the morning 6-12 o'clock. The severity ofischemia and its duration did not correlate with the symptoms.
