冠心病患者ST段缺血型改变的动态心电图分析

Analysis of ST Segment Ischemic Change during Ambulatory Electrocardiographic Monitoring in Patients with Coronary Heart Disease

分析１２０例冠心病患者２４ｈ动态心电网监测结果，表明无症状性缺血型ＳＴ段压低次数明显多于有症状者（Ｐ＜０．０１）；缺血型ＳＴ段压低时伴有典型心绞痛症状者少（占１２．５４％），其平均持续时间明显长于无症状性者（Ｐ＜０．０１）；发作次数白昼占８７．４６％，明显多于夜间（Ｐ＜０．０１），白昼以６～１２时为发作高峰，占５７．９４％；发作时的平均心率明显快于缺血前的平均心率。

cases with coronary heart disease were monitored by ambulatory ECG.The results indicated that the frequency of asymptomatic ischemic ST depression is significantly more than that of symptomatic ischemic ST depression(P<0.01).The frequency of ischemic ST depression complicated with angina pectoris was low(12.54%);87.64%of ischemic ST depression attacks occurred in day time with a peak during 6～12 AM.(57.94%).
