Classical spectral analysis, analysis on a plane of complex frequencies in a rating of oscillations structure of a cardiac rhythm

The article is devoted to the analysis of an opportunity of a parametrical method of the spectral analysis on a plane of complex frequencies in an estimation of reactance of mechanisms of the control of a rhythm of heart separately on the standard frequency ranges. The self descriptiveness of a dispersion of power spectrum of cardiac rhythm variability in estimation of nonstationary oscillations forming peaks of a spectrum, important for diagnostics is shown and can have independent value for physiological interpretation.
