有人假设，心率变异性在低频(LF)和高频(HF)频段的比率可能反映了心脏交感神经控制的变化。在这里，我们测试了24小时动态记录中低频/高频比值的时间稳定性，并将该比值与心脏交感神经控制的既定指标射血前期(PEP)进行了比较。在3.3年的时间内发现了良好的时间稳定性(0.46
It has been hypothesized that the ratio of heart rate variability in the low- (LF) and high- (HF) frequency bands may capture variation in cardiac sympathetic control. Here we tested the temporal stability of the LF/HF ratio in 24-h ambulatory recordings and compared this ratio to the preejection period (PEP), an established measure of cardiac sympathetic control. Good temporal stability was found across a period of 3.3 years (.46 < r
