Table 2.

Reproducibility of heart rate variability parameters recorded in the prone posture on two different days; N = 15.

ICC
TP (ms2) 0.95*
LF (ms2) 0.74
LF (nu) 0.78*
HF (ms2) 0.95*
HF (nu) 0.78*
LF/HF 0.69

ICC = Intraclass correlation coefficient, HF = high frequency of HRV power spectrum, LF = low frequency, LF/HF = ratio of low frequency to high, TP = total power, ms2 = milliseconds squared, nu = normalised unit, * = good reproducibility (ICC > 0.75).
