Simulation of the variable compliance of living systems.
The purpose of this study was to differentiate between the terms generation and simulation which are normally used in the construction of electronic models of biological systems. A technique was adopted based on Miller's theorem to obtain time variable impedances and it was applied to the ventricular compliance simulation. In order to prove experimentally the proposed method, an electronic model of the cardiovascular system using half a heart was designed in which the ventricle is represented by a single time-varying compliance. The voltages which represent the atrial ventricular and aortic pressures and the ventricular volume are provided by the model as outputs.
