Modelling Heart Rate Kinetics
The objective of the present study was to formulate a simple and at the same time effective mathematical model of heart rate kinetics in response to movement (exercise). Based on an existing model, a system of two coupled differential equations which give the rate of change of heart rate and the rate of change of exercise intensity is used. The modifications introduced to the existing model are...
متن کاملA Model of Heart Rate Kinetics in Response to Exercise
We present a mathematical model, in the form of two coupled ordinary differential equations, for the heart rate kinetics in response to exercise. Our heart rate model is an adaptation of the model of oxygen uptake kinetics of Stirling et al. [21]; a physiological justification for this adaptation, as well as the physiological basis of our heart rate model is provided. We also present the optima...
متن کاملDynamic Modelling of Heart Rate Response Under Different Exercise Intensity
Heart rate is one of the major indications of human cardiovascular response to exercises. This study investigates human heart rate response dynamics to moderate exercise. A healthy male subject has been asked to walk on a motorised treadmill under a predefined exercise protocol. ECG, body movements, and oxygen saturation (SpO2) have been reliably monitored and recorded by using non-invasive por...

متن کاملModelling Heart Rate Variability Due to Respiration and Baroreeex
This chapter is devoted to the interactions of heart beat, respiration, and blood pressure oscillations. A nonlinear model is derived which describes the essential parts of the baroreceptor loop: blood pressure wave, baroreceptor activity, cardio-respiratory center, and regulation of heart rate and vascular resistance via the autonomic nerves. Special attention is devoted to the phase response ...
