无症状性心肌缺血患者的动态心电图临床分析

目的：探讨对于无症状性的心肌缺血（SMI）患者进行动态心电图的诊断临床分析。方法：采集本院自2013年1月-2014年1月收治的无症状性心肌缺血患者98例和有症状心肌缺血患者98例,先采用常规心电图进行观察,再采用动态心电图进行观察,总结两种检查情况。结果：经动态心电图检查,无症状性心肌缺血出现313阵次ST段缺血性改变。上午6～12点发作152阵次,占48.56%;下午12～18点发作64阵次,占20.45%;夜间18～24点发作54阵次,占17.25%;凌晨0～6点发作43阵次,占13.74%。98例患者中年龄在60岁以上的患者共发作210阵次,所占比例为67.09%。SMI患者与有症状性心肌缺血患者比较ST段降低幅度,差异无统计学意义（P〉0.05）;发作持续时间比较差异有统计学意义（P〈0.05）。结论：动态心电图应用在无症状性心肌缺血诊断中,可以有效检查出无症状性心肌缺血发作情况,提供了临床工作依据,值得临床应用推广。

Clinical Analysis of Dynamic Electrocardiogram in Patients of Asymptomatic Myocardial Ischemia

Objective： To study for asymptomatic myocardial ischemia in patients with dynamic electrocardiogram diagnosis analysis.Method：98 patients of asymptomatic myocardial ischemia were collected in our hospital from January 2013 to January 2014, the ECG were observed, then the dynamic electrocardiogram were observed, summarizes two kinds of inspection.Result：In the dynamic ECG examination, there were 313 array ST segment ischemia changes in asymptomatic myocardial ischemia patients.6-12 am attack array 152 times, accounted for 48.56%;12-18 in the afternoon attack array 64 times, accounted for 20.45%;the night 18-24 point attack array 54 times, accounted for 17.25%;at 0-6 am attack array 43 times, accounted for 13.74%.In 98 patients over the age of 60 patients with a total of 210 episodes array, the proportion of 67.09%.Compared patients with SMI and symptomatic myocardial ischemia ST segment decreased, no significant difference（P〉0.05）;compared the duration of attack, the difference was statistically significant（P〈0.05）.Conclusion：The application of dynamic electrocardiogram in the diagnosis of asymptomatic myocardial ischemia, can effectively detect asymptomatic myocardial ischemia, provides basis for clinical work, worthy of clinical application.
