| 摘 要： | 目的：探讨冠心病患者无症状心肌缺血阈（MTT）的临床应用价值。方法：记录73例冠心病患者十二导联动态心电图的MIT及其变异性（IV）、每次缺血发作持续时间（Tmi）和ST段最大位移（STm）以及昼夜缺血次数。结果：73例冠心病患者中共检出心肌缺血650次，其中600次属无症状心肌缺血，92．8％在ST段压低时心率加快，夜间MTT值较低，但缺血时间及ST段压低程度明显重于昼间（P〈0．01）。结论：十二导联动态心电图是临床上检测无症状心肌缺血（SMI）的重要方法之一，对临床评估SMI的预后及给药有重要临床意义。

| Abstract: | Objective：To investigate the clinical value of myocardial ischemic thresold （MIT） in silent myocardial ischemia （SMI） patients with CHD.Methods：Using 12-lead dynamic electrocardiography （DCG） to monitor MIT, IV ,Taft, STm ,day and night ischemie episodes in 73 CHD patients.Results：Isehemic episodes were 650 times,600 of them belonged to SMI,92.8% of them had the faster heart rate when ST depression;MIT in night was lower, but TMI and STm were higher than those in day （P〈0.01）.Conclusion：Using 12-lead. DCG to monitor SMI is one of the important methods and has clinical significance to evaluate the prognosis and treatment effects of SMI patients with CHD. |
