【摘要】 目的探讨动态心电图(DCG)与常规心电图(ECG)对儿童心肌炎诊断的差异及临床意义。方法对疑似心肌炎的患儿在做常规12导同步ECG的同时加做24小时12导联DCG,进行对比分析。结果 DCG与ECG各种心律失常及ST-T异常的阳性率分别为69.1%及17.6%,两者具有显著性差异(χ~2=89.1,P<0.01)。所有检测患儿中心肌酶学异常者占49.1%。结论 DCG对儿童心肌炎的诊断、治疗及预后具有重要参考价值。更多还原

【Abstract】 Objective To explore the difference and clinical significance of ECG and DCG in diagnosis of viral myocarditis in children.Method Retrospective analysis of 12-lead ECG and 24-hour 12-lead DCG performed in the suspicious cases of viral myocarditis.Result Positive rate of various arrhythmia and ST-T abnormality shown in 12-lead ECG and 24-hour 12-lead DCG were 69.1%and 17.6%respectively with significant difference(χ~2= 89.1,P<0.01).49.1%of cases had abnormal cardiac isoenzymes.Conclusion DCG has important reference value in the diagnosis,treatment and prognosis judgment of viral myocarditis in children.更多还原
