Simulación de los modelos matemáticos bidominio y desfibrilación para estudiar el restablecimiento del ritmo cardiaco, utilizando el software libre Scilab.

Abstract

This degree work was conducted in order to simulate the mathematical models Bidominium and Defibrillation to study the heart rhythm restoration, by using the free Scilab software, through a bibliographic review which is analized on, the main cardic problems that are demonstrated and the Bidominium and Defibrillation models for electric shocks applied on patients with ventricular fibrillation. The research was base on a quantitative methodology, because numerical data was used that represented a realistic approximation to what happens when applying voltaje to the cardic tissue. Upon using the Scilab program, the mathematical models Bidomio and Defibrillation were simulated that, by means of data entries to emulate the signal through equations, they could be visualized in order to detect heart problems. Finally, it was concluded that with the finite volumen method application, a greater approximation to reality can be presented, for this reason, it is associated with the mesh geometry and the test functions, so the computational effort in this scheme is lower, since volumes are not required to be descretised in their temporary steps explicitly.
