new heart model for better biological system simulation

ABSTRACT

An electronic nonlinear time varying capacitance is designed to simulate the human myocardial performance which cannot be easily programmed on an analog computer. This design makes feasible the use of RLC circuit model for the Pressure-Flow dynamics of the Cardiovascular System with a large number of segments without being limited by the size of the analog computer. The model can be interconnected to the analog computer for studying related problems. Nonlinearity in the suggested model allows for mechanical heart failure to be detected. Systolic time is made variable with heart rate to mirnic reality. Time scale is introduced to allow for the study of slow phenomena like myocardial hypertrophy
