Effects of local activation times on the tension development of human cardiomyocytes in a computational model

Abstract: The human heart is an organ of high complexity and hence, very challenging to simulate. To calculate the force developed by the human heart and therefore the tension of the muscle fibers, accurate models are necessary. The force generated by the cardiac muscle has physiologically imposed limits and depends on various characteristics such as the length, strain and the contraction velocity of the cardiomyocytes. Another characteristic is the activation time of each cardiomyocyte, which is a wave and not a static… Show more

“…In this study, we present a detailed mathematical description of a fully coupled multi-scale model of the human heart building on previous work in cardiac mechanics [25,31,43,[52][53][54][55] and cardiac electrophysiology [49,[56][57][58][59][60]. We parameterize and use state-of-the-art myofilament models based on human physiology to describe membrane kinetics, excitation-contraction coupling and active tension generation in the atria and the ventricles.…”
