- | Both heart beat onsets (R wave time points) as well as sliding beats-per-minute (BPM) are already interesting measures, but most publications refer to summarizes measures when GCR data reported. One of the most common of these is heart-rate variability (HRV). This function computes the power spectral contribution of frequencies in two specified ranges. | + | Both heart beat onsets (R wave time points) as well as sliding beats-per-minute (BPM) are already interesting measures, but most publications refer to summary measures when GCR data reported.
