[The symmetry approach to the assessment of the functional state of the human body].

A multiparameter description of different functional states of human organism has been accomplished on the basis of clinical and polymetric study of healthy and ill humans. The analysis of multiparameter data has been carried out using symmetry approach, image recognition, and graphic simulation. A harmonic correlation between complex physiological parameters of cardiovascular, respiratory, and vegetative nervous system is characteristic for healthy humans. The harmonic correlation changes by 10-15% in humans under stress and by more than 15% in ill humans. The intersystem interaction of physiological functions has been described.
