Abstract

The heart rate influence on chaotic dynamics of the model of interaction between cardiovascular and respiratory subsystems has been studied. The considered model contains both direct and inverse mechanical connection between the heart and the waves generated by the movement of the chest. Applied numerical methods of the theory of dynamical systems are used. It is shown how an increase in heart rate can affect the wave characteristics of the heart.

Key words: cardiovascular system, respiratory system, limited excitation, chaos.
