摘要
目的分析病毒性心肌炎(VMC)患儿心率及心率变异性(HRV)的特点。方法将150例VMC患儿作为观察组,同期100例健康儿童作为对照组。2组儿童均进行24 h动态心电图检查,记录24 h最快心率、最慢心率、平均心率,以及醒时和睡时最快心率、最慢心率,并分析HRV。结果与对照组比较,观察组不同年龄段的患儿24 h最慢心率及平均心率均显著加快;8~16岁患儿24 h最快心率显著减慢。与对照组比较,观察组不同年龄段的患儿醒时及睡时最慢心率均显著加快;仅8~16岁患儿睡时及醒时最快心率显著减慢。除2组4~7岁患儿R-R间期平均值的标准差(SDANN)之间无显著差异以外,观察组各年龄段HRV指标均显著低于对照组。结论 VMC患儿不同年龄段的最慢心率及平均心率均增快,年龄偏大的患儿最快心率减慢;各年龄段HRV指标普遍降低。将心率及HRV结合起来可更全面、更客观地指导VMC诊断并判断预后。
Objective To analyze the characteristic of heart rate and heart rate variability(HRV) in children with viral myocarditis(VMC).Methods One hundred and fifty children with VMC were divided into observation group,and another 100 healthy children were divided into control group.The two groups both received 24 h dynamic electrocardiogram.The fastest,slowest,average heart rate in 24 h,and fastest,slowest heart rate at waking up and sleeping state were recorded.The HRV was analyzed.Results Compared with the control group,the slowest,average heart rate in 24 h in children with different ages in the observation group obviously accelerated,while the fastest heart rate in 24 h in 8-16-year-old children obviously slowed down.Compared with the control group,the slowest heart rate at waking up and sleeping state in children with different ages in the observation group obviously accelerated,while the fastest heart rate at waking up and sleeping state in 8-16-year-old children obviously slowed down.Except that there was no significant difference of SDANN in 4-7-year-old children of the two groups,the indexes of HRV at different ages in the observation group were significantly lower than that in the control group.Conclusion The slowest and average heart rate in 24 h in VMC children with different ages obviously accelerate,while the fastest heart rate in elder children obviously slow down.The indexes of HRV at different ages generally slow down.The combination of heart rate and HRV can guide the diagnosis and prognosis of VMC more comprehensively and objectively.
