The Importance Of Specifying Rr Interval Normalization Method

Abstract

The main objective of this article is to bring attention to RR intervals resampling. Many researchers dealing with HRV problematic neglect to mention which algorithm they are using in their research. Some of the commonly used methods are presented here and how an algorithm choice can affect final results of HRV spectral analysis is shown. Power spectrum for each method was computed and power of commonly used measures (HF & LF) is presented in table to highlight the possible differences.
