Abstract :The new version of the hydro-electro-mechanical system insert ignore into journalissuearticles values(HEMS); is modeled via 14 serially connected electrical equivalent circuits resulting in an integrated equivalent circuit. The new model accepts a group of variables and even examines the interaction between them. This paper introduces an improved integrated new model of the heart by replacing the monolithic equivalent structures with segmental comprehensive equivalents. Windkessel Model insert ignore into journalissuearticles values(WM); is a model of the relationships between aorta, aortic valve and left ventricle. Based on WM, the integrated new model was developed and simulated. The model’s main focus is to define the dynamic properties of the system by a set of ordinary differential equations, and solving them using Ode23, a method for the solution of a closed-loop system. Using Matlab based Ode23 method; time-dependency of pressure, volume and flow were obtained. In case, short computation time and high accuracy are needed, then ode23 is used. The model may be used to analyze complex processes in the heart and blood vessels. The new HEMS model has potential use for hemodynamic simulation of diseases, cardiovascular disorders, and special congenital heart diseases; such as ASD, VSD and PDA.
