Nonlinear reaction-diffusion models of self-organization and deterministic chaos: Theory and possible applications to description of electrical cardiac activity and cardiovascular circulation

摘要

The paper shows that analytical dynamic models coupled with the availablesignal processing methods could be used for describing theself-organization and chaos degree in the heartbeats propagation andpressure pulses in ventricular at ejection phase. We proposed a unitanalytical approach that could be associated with real ECG and pressurepulses signal processing. Our findings confirm that the real-time computermonitoring of the main cardiovascular parameters obtained by the use ofanalytical models and verified by signal processing of real clinical datamay be considered as available method for measuring and controllingself-organization and chaos degree in pulse propagation.
