目的：探讨冠心病无症状性心肌缺血的动态心电图（DCG）的临床特征。方法回顾性分析我院收治的56例冠心病患者动态心电图诊断情况。结果无症状性心肌缺血发作131阵次。其中上午6~12点发作占50.38%；下午12~18点占18.32%；凌晨0~6点发作占31.30%。其中年龄在60岁以下的患者占37.40%，年龄在60岁以上占62.60%。结论动态心电图是监测冠心病无症状性心肌缺血的重要手段。%Objective To investigate the clinical characteristics of dynamic electrocardiogram (DCG) of coronary heart disease with asymptomatic myocardial ischemia. Methods A retrospective analysis of 56 cases of CHD diagnoses in our hospital were chosen.ResultsAsymptomatic myocardial ischemia attack array 131 times. In the morning 6~12 point attack accounted for 50.38%; 12~18 p.m. accounted for 18.32%, at 0~6 onset accounted for 31.30%. Among them patients below age 60 years, accounted for 37.40%, accounting for 62.60% over the age of 60.ConclusionHolter monitoring for coronary heart disease is an important means for asymptomatic myocardial ischemia.
