摘要
目的研究不同年龄心肌炎患儿的心率及心率变异(HRV)改变的特点和相关性。方法对120例心肌炎患儿进行24h全程动态心电图检查,分析心率及HRV。结果不同年龄心肌炎患儿心率范围不同,年龄越小心率越快;24h内连续正常R-R间期的标准差(SDNN);5分钟正常R-R间期标准差的平均值(SDNN index);全程相邻R-R间期差值的均方根值(rMSSD);相邻R-R间期之差大于50ms的心搏次数占总心搏次数的百分比(PNN50)。随年龄增长其数值增高,24h内每5分钟R-R间期平均值的标准差(SDANN);男女HRV比较无差异。结论心肌炎患儿HRV短时动态心电图检测不能良好显示患儿HRV病态变化,长时间、多指标对病情检测更可靠。
Objective To assess heart rate and heart rate variability（HRV） in the children with myocarditis. Methods Continuous electrocardiographic monitorization by 24 - hour Holter recordings was performed in 120 children with myocarditis. Results The rhythm varied among different ages in children. Heart rate decreased while children age increased. Significant differences of SDNN, SDNNindex, rMSSD, PNNso were shown among different age groups. The data was significantly higher while children age increased. No changing was found between male and female. No differences of SDANN were shown among different age groups. Conclusion The data of HRV decreased while children age decreased. We advocate attaching importance to continuous electrocardiographic monitorization.
