Modeling of the Cardiovascular System and Systolic Insufficiency Using Equivalent Electronic System

Cardiovascular diseases are one of the most common causes of death in the world. The modelling systems are useful for knowing, controlling and preventing cardiovascular abnormalities. Lumped models are among the existing mathematical simulations widely used to model the operation of the cardiovascular system. In this study, we have used MATLAB software and the Simulink toolbox to present an electronic circuit of the cardiovascular system, which is able to show the normal operation of the system. Then, we studied the systolic insufficiency by variation of the circuit elements. Our results showed that the left ventricular ejection fraction, during systolic insufficiency, was significantly reduced compared to the healthy heart. Moreover, the peak aortic flow and the ejection fraction were also decreased.
