摘要
目的 探讨动态心电图对儿童短阵发作症状的诊断价值。方法 75例有短阵发作症状儿童分为病毒性心肌炎组(n=40)和对照组(n=35),分别监测动态心电图和常规心电图。结果 病毒性心肌炎组动态心电图阳性率925%,对照组228%,两者有显著性差异(χ2=377,P<005),病毒性心肌炎的动态心电图阳性率(925%)显著高于常规心电图(575%)(χ2=131,P<001)。结论 症状发作时动态心电图改变对病毒性心肌炎有诊断意义,对有短阵发作症状患儿应作动态心电图监测。
Objective To explore the diagnostic value of the ambulatory electrocardiography(DCG)in children with paroxysmal symptoms.Methods 75 cases with paroxysmal symptoms were divided into two groups:the virus myocarditis group( n =40)and the control group( n= 35),both were detected by DCG and ECG.Results Total positive rate with DCG in virus myocarditis group was significantly higher than that in control group(92 5%vs22 8%,χ 2=37 7 P <0 005);total positive rate of DCG was significantly higher than that of ECG in virus myocarditis(92 5%vs57 5%,χ 2=13 1 P <0 01).Conclusion DCG is more effective in diagnosing myocarditis.It suggests that DCG monitoring should be done as soon as symptomatic attack is found.
