FFT denotes that a given HRV parameter was calculated by using Fast Fourier Transform, while AR indicates that the HRV spectrum was calculated with autoregressive method. Corrected HRV parameters were calculated as follows: corr-SDNN, SDNN/mRRˆ2.2; corr-RMSSD, RMSSD/mRRˆ3.0; corr-pNN50, pNN50/mRRˆ5.0; FFT corr-VLF, VLF/mRRˆ3.0; AR corr-VLF, VLF/mRRˆ4.0; for both FFT and AR: corr-LF, LF/mRRˆ4.0; corr-HF, HF/mRRˆ5.0; corr-TP1, TP1/mRRˆ5.0; corr-TP2, TP2/mRRˆ5.0; corr-LF/HF, LF/HF∗mRRˆ1.0; corr-nLF, nLF∗mRRˆ1.0; and corr-nHF, nHF/mRRˆ0.5.
