Abstract
Nesse trabalho, apresenta-se uma das aplicações da modelagem matemática no sistema cardiovascular, a sua utilização na estimação do volume ventricular esquerdo - um parâmetro fundamental no diagnóstico de doenças cardíacas. Para isso, prepara-se um molde de um ventrículo esquerdo bovino, seu volume real é determinado e, então, comparado com os resultados obtidos por métodos matemáticos médicos e com um novo método proposto, baseado na integral de revolução de uma função polinomial específica. Os resultados preliminares indicam que o método proposto é mais eficiente que os métodos médicos, com diferença de apenas 3,5% do volume real.

Mathematical modeling and the determination of a new method of the ventricular volume calculation
ABSTRACT
In this work, we presented one of the applications of mathematical modeling to the cardiovascular system, its use in the estimation of the left ventricular volume, which is a basic parameter in the diagnosis of heart disease. To do that, a mold of a bovine left ventricle is prepared, its real volume is determined and then it is compared to the results achieved by medical mathematical methods and with a new proposed method, based on the integral of revolution of a specific polynomial function. Preliminary results indicate that the proposed method is more efficient than medical methods, with a difference of only 3.5% of the actual volume.
Keywords: Mathematical Modeling. New Calculation Method. Ventricular Volume.
