Abstract

A theoretical model is proposed to estimate the total behavior of cardiovascular system. Ventricular function is expressed by a time varying capacitance with internal impedance and passive elastance. Arterial system is expressed by aortic inertance, aortic valvular resistance, fluid resistance, aortic and peripheral compliance. The present model can reproduce the physiological pressure curves and reactions to changes in afterload impedance and ventricular viscous resistance. The present model can be used to estimate the total hemodynamical changes in the cardiovascular system of the patient without invasive examination
