摘　　要：目的探讨DC、DRs检测对血管迷走性晕厥(VVS)患儿迷走神经张力的评估价值。方法选取我院2018年2月至2021年2月期间收治的72例VVS患儿为观察组,同期健康儿童72例作为参考组。检测两组的24小时心电信号,比较两组的HRV指标、DC及DRs。采用Pearson相关性检验分析DC与HRV指标、LF、HF的相关性。结果观察组的SDNN、SDANN、LF均小于参考组,RMSSD、HF、DC以及DR4均大于参考组(P<0.05)。DC值与SDNN、SDANN、RMSSD和HF值呈正相关,与LF值呈负相关(P<0.05)。结论临床在诊断血管迷走性晕厥时,检测DC值、DRs值可从不同侧面定量评估迷走神经张力水平,具有较高的临床应用价值。Objective To explore the value of DC and DRs detection in evaluation of vagus nerve tension of children with vasovagal syncope(VVS).Methods A total of 72 children with VVS admitted to our hospital from February 2018 to February 2021 were selected as observation group,and 72 healthy children during the same period were selected as reference group.The 24-hour ECG signals of the two groups were detected,and the HRV indicators,DC and DRs of the two groups were compared.Pearson correlation test was used to analyze the correlations of DC with HRV index,LF and HF.Results The SDNN,SDANN and LF of the observation group were all lower than those of the reference group,while the RMSSD,HF,DC and DR4 were all higher than those of the reference group(P<0.05).DC value was positively correlated with SDNN,SDANN,RMSSD and HF values,and negatively correlated with LF value(P<0.05).Conclusions In the clinical diagnosis of vasovagal syncope,the detection of DC value and DRs value can quantitatively evaluate the level of vagal tone from different aspects,which has higher clinical application value.
