动态心电图和常规心电图在诊断小儿病毒性心肌炎中的对比研究

Comparative study of dynamic electrocardiogram and routine electrocardiogram in the diagnosis of infantile viral myocarditis

目的 探讨动态心电图（Dynamic electrocardiogram,DCG）诊断小儿病毒性心肌炎的价值.方法 对152例病毒性心肌炎患儿的动态心电图和常规心电图（Electrocardiogram,ECG）检测结果进行对比,分析DCG在病毒性心肌炎患儿心律失常及心肌缺血检出中的意义.结果 152例患儿中动态心电图结果异常139例,常规心电图异常86例,二者比较有统计学差异（x2=48.041,P＜0.001）.结论 动态心电图可提高病毒性心肌炎患儿心律失常及心肌缺血的检出率,并可监测到普通心电图难以观察到的心电变化,可为小儿病毒性心肌炎诊断提供可靠依据.

Objective To explore the clinical value of dynamic electrocardiogram （DCG） in the diagnosis of infantile viral myocarditis.Methods The results of DCG and routine electrocardiogram （ECG） of 152 children with viral myocarditis were analyzed to determine the clinical value of DCG in the diagnosis of infantile viral myocarditis.Results One hundred and thirty-nine patients showed abnormal DCG while 86 patients showed abnormal ECG.There was significant difference between DCG and ECG （x2 =48.041,P 〈0.01）.Conclusions DCG can improve the detection rate of cardiac arrhythmia and myocardial ischemia,and it can be used to monitor the changes which are difficult to be observed the ECG.DCG can provide a reliable basis in diagnosis of viral myocarditis in children.
