WebMay 14, 2024 · Note: The RR interval is given in seconds (RR interval = 60 / heart rate). Bazett and Fridericia are logarithmic corrections whereas Hodges and Framingham are linear correction formulae Henry Cuthbert Bazett derived his formula in 1920. Bazett formula is the most commonly used due to its simplicity. 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.
