A new paper is published in Journal of Basic and Applied Physics (JBAP): Understanding the Electro-mechanical Activation of the Myocardium
In order to contribute to the study of the Helical Myocardial Ventricular Band, a computational model to simulate the behaviour of the myocardial tissue, mainly based in the fibres, is presented. It is based in considering the path described by the band as a preferential path described by fibres, and in considering that the propagation of the electromechanical activation follows this path. The model describes two basic aspects of the myocardial tissue: an active part that generates the contraction and a passive part due to the connective tissue. Interaction of these parts generates governing equation. The simulation of the model is based on generating a propagation of electrical stimulus that follows the preferential path described by the band. As a consequence of the application of it, a deformation following the same path of the stimulus is obtained. The results obtained in the computational are compared with others works in literature with real hearts to conclude that, if the electro-mechanical activation sequence in the myocardium coincides with the path described by the HMVB the path and the delay observed in the shortening of the fibres are according with the expected and observed behaviour in real hearts.
