Abstract:
The main stages of investigation into the changes of the heart rate in human (HRH), are presented. A satisfactory coincidence of results of the HRH oscillation power estimation within two frequency ranges obtained with the aid of two techniques: by the Yamamoto algorithm and by search for sources of non-harmonic oscillations, was shown.
