Abstract
For the improvement of the quality of life of the patients with artificial heart system, it is important to detect the information of the circulatory regulatory system. Baroreflex system is an important control system when we consider the HOMEOSTASIS of the cardiovascular system. In this study, we studied an artificial baroreflex system using an electrical circuit simulation and the chronc animal experiments with the artificial heart system. As the results, an electrical circuit simulation showed chaotic dynamics according to the increase of the time lag in the baroreflex loop. Furthermore, an automatic control algorithm simulating the baroreflex system with an artificial heart system could generate the chaotic hemodynamics in the chronc animal experiments. These results suggest that Baroreflex system plays an important role when we consider the determitistic chaos in the hemodynamic parameters.
