目的了解小儿心律失常引起心率变异(HRV)指标的变化。方法对20例心律失常患儿进行24h动态心电图检查,检测其心律失常引起的心率变异指标与20例健康儿童对照组比较。结果心律失常患儿组的SDNN与SDANN值降低。结论心率变异是评价心脏自主神经系统功能的指标。心律失常患儿的交感神经与迷走神经的调控功能明显受损,应引起临床上的高度重视,并给予积极治疗。
Objective To understand the changes of heart rate variability (HRV) in children with arrhythmia. Methods Twenty children with arrhythmia were examined by 24 h electrocardiogram (ECG), and the indexes of heart rate variability induced by arrhythmia were compared with those of 20 healthy children. Results SDNN and SDANN values decreased in children with arrhythmia. Conclusion Heart rate variability is an indicator of cardiac autonomic nervous system function. Arrhythmia in children with sympathetic and vagal nerve regulatory function was significantly impaired, should cause clinical attention, and give active treatment.
