[摘要] 目的 研究冠心病无症状性心肌缺血患者应用动态心电图诊断的临床价值。 方法 方便选取在该院2016年8月—2017年8月接受治疗的80例冠心病无症状性心肌缺血患者分为观察组和对照组，对照组(40例)和观察组(40例)分别采用常规心电图和动态心电图诊断。比较两组患者临床诊断总体有效率、病症特异性诊断准确率和ST段的位移值指标情况。 结果 观察组临床诊断有效率为80%，明显高于对照组(55%)；观察组病症特异性诊断准确率为95%(38/40)；对照组诊断准确率为75%(30/40)；ST段的位移值指标情况均明显优于对照组，组间差异有统计学意义(P<0.05)。 结论 冠心病无症状性心肌缺血患者应用动态心电图进行诊断的准确率较高，应该在临床中进行推广。

    [Abstract] Objective To study the clinical value of dynamic electrocardiogram (ECG) in the diagnosis of silent myocardial ischemia in patients with coronary heart disease. Methods 80 patients with coronary heart disease with asymptomatic myocardial ischemia from August 2016 to August 2017 were convenient selected and divided into the observation group and the control group. The control group (40 cases) and the observation group (40 cases) were diagnosed by routine electrocardiogram and dynamic electrocardiogram respectively. The overall clinical effective rate ......
