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.
BIOPAC is introducing Biopac Student Lab Home (BSL HOME)—a new product specifically geared towards teaching physiology labs remotely so students can still get hands-on, practical lab experience if social distancing and stay-at-home orders keep them out of the lab..
BSL HOME will allow your students to conduct physiology labs in the safety of their own home, dorm room, or any remote location.
