The Method of Identification of a Mathematical Model for the Cardiovascular System Response Dynamics to Exercise Stress

Abstract

The process of rehabilitation after heart disease is a major problem today. Existing mathematical model is phenomenological. This paper presents a mathematical model of the heart rate and pressure under the influence of physical activity. The identification of the presented model based on the modified gradient Levenberg-Markvadt method supplemented with the procedure of initial ratios choice is introduce for the first time.
