HF, high frequency; LF, low frequency; pNN50, proportion of adjacent RR intervals more than 50 ms different; rMSSD, root mean square of difference of successive RR intervals;

*r*_{s}, Spearman correlation coefficient; SD, mean of all five minute standard deviations of RR intervals; SDANN, standard deviation of five minute RR intervals; SDNN, standard deviation of all RR intervals from the mean.
