title: [Analysis for the Persistence of Various Regimens of Heart Rate Dynamics by Computer Modeling].
abstract: A computer modeling revealed the following three regimens of heart rate dynamics: linear dynamics, "1st degree chaos", and "2nd degree chaos". This work was designed to study the persistence of these regimens by the method of Hurst. Our investigation showed that the Hurst index is highest for "2nd degree chaos" (H = 0,671 ± 0,028). The Hurst index for the "1st degree chaos" regimen was lower than that for "2nd degree chaos" (H = 0,473 ± 0,015). An increased persistence of cardiac rhythmogenesis in the "2nd degree chaos" regimen illustrates the non-stationarity and prognostic instability of these processes, which contributes to a high risk of heart diseases.
