Abstract

The article is devoted to analysis of random uncertainties of heart rate variability indices. The article contains the algorithm of Hurst indicator calculation based on RS-method and algorithm of calculation of fluctuation coefficient based on Detrended Fluctuation Analysis. The dependence between relative uncertainty of heart rate variability indices and absolute uncertainty of measurement of beat-to-beat intervals is estimated. The conclusion about sensitivity of heart rate variability indices used in the article to the uncertainty of measurement of beat-to-beat intervals is made.
