摘要
目的:探讨儿童血管迷走性晕厥(VVS)与心率变异性(HRV)的变化。方法:采用12导联同步心电图及动态心电图对52例VVS患儿及30例健康儿童的HRV进行测量。结果:SDNN、SDANN及RMDNN病例组较对照组小,且病例组SDNN、RMDNN与对照组比较差异有统计学意义(P<0.05);HUTT阳性和阴性间HRV比较差异无统计学意义(P>0.05)。结论:VVS的发病机制与交感神经和副交感神经调节障碍有关。HUTT作为诊断VVS的金标准,其阴性者不能除外,HRV对VVS患儿发生心肌缺血、心律失常等心血管事件具有一定的预测价值。
Objective：To investigate the children with vasovagal syncope （VVS） and heart rate variability（HRV） changes.Method：HRV were measured by 12 synchronization ECG and dynamic ECG in 52 cases of VVS and 30 cases of healthy children.Result：SDNN,SDANN and RMDNN were compared with the control group decreased,and the cases in groups SDNN,RMDNN compared with the control group had significant difference（P0.05）.Conclusion：The pathogenesis of VVS and the sympathetic and parasympathetic regulation disorders.HUTT as the gold standard for the diagnosis of VVS,its negative except HRV of VVS patients not arrhythmia during myocardial ischemia,and it has certain value in predicting cardiovascular events.
