| Abstract(in English) | Linear system analysis was applied for the coronary circulation system. The system was expressed by an equivalent electrical circuit. It is consisted of the arterial and venous sites each of which is separated to the epicardial and the end cardial regions. The mechanical properties of the vessels were expressed by resistance and capacitance which values were adopted from the reported animal experiments. The system was expressed by 4 linear differential equations. The control inputs to drive the blood during the systolic phase were set by the active elastance of cardiac muscles. At the physiological resistance and capacitance, the system was stable and controllable. Expressing the coronary arterial sclerosis by reducing the capacitance and arterial stenosis by increasing the resistance, we can evaluate the pathophysiological changes in coronary circulation. |
