| 摘 要： | 目的:探讨小儿心肌炎的心率变异性。方法:采用ECG-LA2.OGold型心电综合分析系统,描记肢体导联采样5分钟,应用时域及功率谱分析法,通过计算机计算出全部R-R间期的标准差(sDNN),极低频(VLF)低频(LF)高频(HF)。结果:以SDNN<27ms为阳性诊断标准,将57例小儿心肌炎病儿分为两组,一组SDNN<27ms共17例,病情较重,另一组SDNN>27ms共41例,病情较轻。结论:病情较重的心肌炎患儿短程HRV降低SDNN<27ms。

| Abstract: | Objective: To explore the heart rate variability of myocarditis in children. Method: Using Model ECG - LA2.0 Cold electrocardioanalysing System to record five minutes through limb leads, adopting time domain and power spectrum analysing methods, the standard diviation of NN or RR intervals(SDNN) , verylow -frequency(VLF) , low - frequency( LF) and high - frequency(HF) were calculated by computer. Result: Taking SDNN < 27ms as diagnostic point of abnormality, the 57 cases were divided in to two groups. One group is 17 cases whose illness are serious (SDNN < 27ms) . Another group is 41 cases whose illness are light (SDNN > 27ms). Conclusion:The HRV is decreased and SDNN < 27ms in childred with serious myocarditis. |
