Cardiac rythm variability analysis as an index of psychological relaxation

The results of psychophysiological study and those of spectral analysis of cardiac rythm variability during psychological relaxation of atomic power station operators account for physiological indicators for the negative states such as neurotization, depression, functional reserve reduction. Cardiac rythm variability figures based on spectral analysis to define the level of centralization, vegetative balance and the total spectre capacity showing the functional reserve. Spectral analysis high efficiency use to govern and monitor the psychological relaxation is demonstrated.
