目的:总结小儿病毒性心肌炎的动态心电图改变特点并作以分析,为临床诊治疾病提供参考资料。方法:对40例经临床诊断为小儿病毒性心肌炎的患儿进行24小时动态心电图监测,并分析其特点。结果:本组40例均检测出均有心电图改变,各种心律失常37例,占发病率的92.5%,在心律失常中,以过早搏动最常见,有24例,占64.9%;仅有ST段、T波改变12例,占发病率的30%;移位心动过速4例,占10%;传导阻滞12例,占30%;室性心律失常5例,占12.5%;发生低电压13例,占32.5%。结论:动态心电图监测能提高心肌患儿心律失常检出率,可以监测到普通心电图难以观察到的心电变化,对临床诊断小儿病毒性心肌炎提供了重要的诊断依据,为临床的治疗提供宝贵的参考资料。
OBJECTIVE: To summarize the characteristics of dynamic electrocardiogram changes in children with viral myocarditis and to analyze them for reference in clinical diagnosis and treatment of diseases. Methods: 40 cases of children with clinical diagnosis of viral myocarditis in children with 24-hour Holter monitoring and analysis of its characteristics. Results: The electrocardiogram changes were detected in all 40 cases in this group, including 37 cases of various arrhythmias, accounting for 92.5% of all cases. In arrhythmias, premature beat was the most common, 24 cases (64.9%); only ST segment, T wave changes in 12 cases, accounting for 30% of the incidence; displacement of tachycardia in 4 cases, 10%; conduction block in 12 cases, 30%; ventricular arrhythmia in 5 cases, accounting for 12.5%; occurred Low voltage in 13 cases, accounting for 32.5%. Conclusion: Holter monitoring can improve the detection rate of cardiac arrhythmia in children with cardiac arrhythmia, and can monitor ECG changes which are difficult to be observed in common ECG. It provides an important diagnostic basis for clinical diagnosis of viral myocarditis in children and provides valuable clinical treatment Reference material
