AcqKnowledge calculates heart rate variability (HRV) using the Welch Periodogram and least squares de-trending methods.
To properly select the parameter values needed for the calculation of the Power Spectral Density, which is the “work-horse” tool for Heart Rate Variability analysis, a brief tutorial is presented, including an R-R Interval Processing Approach.
The Welch Periodogram is a method by which a large time-sampled waveform can be frequency-transformed by partitioning the data into shorter segments, transforming each segment, then, averaging the results over all the segments to create a composite frequency space waveform.
