MODELLING OF CARDIOVASCULAR SYSTEM REGULATION

The article deals with principles of cardiovascular system regulation. The work describes physiological basis of selected regulation mechanisms such as autoregulation and baroregulation. An overview of cardiovascular system models is presented. The paper contains description of linear regulation models and also models containing nonlinear phenomenon. The article describes implementation of heart rate and vascular resistance regulation to existing model of arterial system based on the principle of electromechanical analogy. The implemented regulation model is based on baroreceptor regulation application. There are analysed characteristic properties of baroreceptor regulation such as saturation, hysteresis or step change in baroreceptor impulse rate
