WebAnswer (1 of 3): Adding to an earlier answer, RR intervals actually vary all the time. This is quite normal, and indeed the more the variability, generally the more healthy you are. So it is valuable to measure CHANGES in RR intervals. In order to do this, it is important to have good pulse data ... WebIn studies of heart rate variability (HRV), however, heart rate is modelled as as a quasi-continuous signal, and the RR interval series is used to obtain samples of that signal at more frequent intervals. The simplest and in many ways the best way to do this is to calculate the reciprocal of each interval in minutes; to do so, use ihr.
