  1. RR mean, the mean value of RR intervals; SDNN, standard deviation of RR intervals; RMSSD, root mean square of successive differences; PNN50, percentage of the number of successive heartbeats differing > 50 ms; HF, high frequency power; LF, low frequency power; TP, total power; LF/HF, ratio of low frequency to high frequency; C1d, contributions of heart rate decelerations to short-term heart rate variability; C2d, contributions of heart rate decelerations to long-term heart rate variability. Data are P values of Wilcoxon signed-rank test
