The analysis of heart rate variability (HRV) has become a tool for noninvasively detecting the cardiovascular modulation of autonomic nervous system (ANS). Traditional analysis in frequency-domain mainly includes calculating the power and the peak frequency of each physiological frequency component. Whether employing the non-parametric or parametric method to estimate the power spectrum density (PSD), the approximate stationarity of HRV is presupposed. However, only in short-term analysis can… CONTINUE READING
