摘　　要：目的分析比较动态心电图与常规心电图用于老年无症状性心肌缺血诊断的差异。方法选择本院2017年1月至2019年6月收治的无症状性心肌缺血患者50例,所有患者均给予常规与动态心电图检查,比较两种心电图检查方法的诊断效果。结果常规心电图检查诊断准确率为60.0%,动态心电图诊断准确率为88.0%,差异有统计学意义(P<0.05)。动态心电图显示无症状性心肌缺血发作具有明显规律,12:00~13:00为该疾病发作的高峰时段,夜间1:00~2:00为发作低谷时段。动态心电图对患者室性期前收缩、束支传导阻滞以及房性期前收缩等心律失常情况的检出率均显著较高(P<0.05)。结论老年无症状性心肌缺血应用动态心电图诊断的临床效果显著,能够更好地反映患者的疾病发作特性,可推广应用。Objective To analyze and compare the difference between dynamic electrocardiogram and conventional electrocardiogram in the diagnosis of asymptomatic myocardial ischemia in the elderly.Methods A total of 50 patients with asymptomatic myocardial ischemia admitted to our hospital from January 2017 to June 2019 were selected.All patients were given routine and dynamic electrocardiogram examination to compare the diagnostic effects of the two methods.Results The diagnostic accuracy of routine electrocardiogram examination was 60.0%,and that of dynamic electrocardiogram was 88.0%,with statistical difference(P<0.05).Dynamic electrocardiogram showed that asymptomatic myocardial ischemic attack had obvious regularity.The peak period of the attack was from 12:00 to 13:00,and the low period was from 1:00 to 2:00 at night.Dynamic electrocardiogram(DCG)showed significantly higher detection rates of ventricular prephase contraction,bundle branch block,atrial prephase contraction and other arrhythmias(P<0.05).Conclusion Application of dynamic electrocardiogram(DCG)in diagnosis of asymptomatic myocardial ischemia in the elderly has a significant clinical effect,which can better reflect the disease onset characteristics of patients and can be popularized.
