Model Based Cardiac Control System For The Left Heart Using LabView

Abstract

With advancements in biomedical engineering research several mathematical models were developed for cardiovascular system, but their utilization has hindered due to scope limitations. This study aims to develop a simulation program to study the phenomena of filling and ejection in the Human Heart. This study investigates the Control Scheme for a transfer function Model-Based Cardiac System through the simulation tool LabVIEW. It is possible to simulate and analyze essential physiological features of the human heart by correlating the physiological system into an equivalent Mathematical Model such as the Transfer Function model. The blood filling and ejection models of the human heart are demonstrated in this work. The circulatory graphical plots of the Human Cardiovascular Control System during the phenomena of blood filling and ejection are presented and discussed. The performance of the control scheme successfully aids in retaining the significant parameters at the threshold level. The mathematical model can be used to gain deeper insights into the functioning of the human heart. It also aids in the development of an accurate model of the cardiovascular system that helps in analyzing the pressure pulse in the arteries of the human heart. This study paves a way for further research studies in Artificial Pacemaker as a future scope.
