Models of reactions of human heart as nonlinear dynamic system to cosmic and geophysical factors

The paper analyzes theoretical models of the adaptive modes of generation and stability of human heart as a nonlinear point source. The analysis encompasses only ECG time-domain dynamics. To solve the general problem of the study of the adaptive changes of the cardiosignal under the action of external periodic force and parametric noise, a new dynamic model is proposed, which incorporates two control physical parameters: power of signal generation and coefficient of diffuse signal scattering. For the entire set of parameters, the examined modeled nonlinear system demonstrated a number of various performance modes ranging from steady-state periodic and quasi-periodic states to chaos. The model showed that variations in cosmic, geophysical, and weather conditions in the frequency range of 0.1-0.9 Hz produce the greatest biotropic influence. © 2010 Springer Science+Business Media, Inc.
