218例冠心病患者24小时动态心电图分析

Analysis of 24 hour dynamic electrocardiograms in 218 patients with coronary heart disease

对２１８例冠心病人行２４ｈ动态心电图监测。结果：检出心律失常４１２例次（９２．２５％），常规静息心电图检出心律失常８１例次（３７．１５％），二者有显著差异（Ｐ＜０．０１）；冠心病人常见的心律失常依次为：室性早搏、房性早博、房性心动过速；冠心病心绞痛患者１８７例显示ＳＴ段压低＞１．０ｍｍ，其中心肌缺血７５％不伴有心绞痛发作。提示无症状心肌缺血可作为不稳定型心绞痛发作的一项重要预后指标。

Two hundred and eighteen cases of coronary heart disease were monitored by electrocardiography continuously for 24 hours. There were detected 412 occurrences of arrhythmia (92.25%), but only 81 occurrences of arrhythmia in quiescent electrocardiogram,the difference being significant (P<0.01).The most common arrhytnmia was ventricular premarure beats followed by atrial premature beats and atrial tachycardial. ST segments depressed>0.1 mm in 187 patients with angina pectoris and 75% of patients with myocardial ischemia had no angina pectoris episodes. It is suggested that a symptomsatic myocarial ischemia can serve as an important index for unstable angina pectoris episodes.
