摘　　要：目的研究病毒性心肌炎患儿心率变异(HRV)的变化特点。方法:选用74例儿童为研究对象,分为正常对照组和心肌炎组,进行心率变异检测分析。结果:与正常儿童比较,心肌炎患儿心率增快,心率变异指标降低。结论:心肌炎患儿HRV降低源于心肌缺血及相关炎性因子作用导致心脏自主神经系统总体功能受损,其病变对副交感神经系统的影响比交感神经系统更明显。Objective：To investigate the changes of heart rate variability（HRV） in children with viral myocarditis .Methods：74 children were enrolled in this study. They were divided into two groups as follows：group 1 （healthy children）, group 2 （children with myocarditis ）. They were received examination of 24 hours dynamic electrocardiograms respectively and analyzed HRV. Results：In children with myocarditis, the heart rate was significantly faster while HRV was significantly lower than that in the healthy group.Conclusion：The data of HRV is decreased by myocardial ischemia and inflammatory factors of myocarditis. The ischemia and factors harm the autonomic nerve. Myocarditis has more severed effect to parasympathetic nervous system than sympathetic nervous system.
