Abstract

The proper functioning of the Cardiovascular system is dependent on several tissues like the heart, blood, arteries, and veins. These tissues are in contact with each other. In this paper, we present a cardiovascular model based on equivalent mathematical relations in Simulink environment for analyzing the changes that occur due to baroreceptors. The system aims to quantify and depicts the relation between various cardiac parameters like blood pressure, heart rate, stroke volume for different delays. The cardiovascular output is determined by stroke volume and heart rate, with heart rate being determined by blood pressure. A change in blood pressure will cause the appropriate variation in heart rate and cardiac output individually. So, in this work, a closed-loop Simulink system is used for analyzing the variation through the baroreflex function with necessary feedback. The simulation response of the various cardiac parameters for different time delays is analyzed using MATLAB-Simulink.

心血管变异性模型中气压反射功能的分析

心血管系统的正常运作依赖于几个组织，如心脏、血液、动脉和静脉。这些组织相互接触。本文在Simulink环境中建立了一个基于等效数学关系的心血管模型，用于分析压力感受器引起的心血管变化。该系统旨在量化和描述各种心脏参数之间的关系，如血压，心率，不同延迟的中风量。心血管输出量由搏量和心率决定，心率由血压决定。血压的变化会引起心率和心输出量的适当变化。因此，本文采用闭环Simulink系统，通过具有必要反馈的气压反射函数来分析其变化。利用MATLAB-Simulink分析了各种心脏参数在不同时延下的仿真响应。
