Subcellular dynamics is coupled with a model of tissue mechanics, which is in turn coupled with a Windkessel model for blood circulation. Our numerical results show that the proposed model is able to provide a physiological response to changes in certain variables (end-diastolic volume, total peripheral resistance, contractility). We also show that our model is able to reproduce with high accuracy and with a considerably lower computational time the results that we would obtain if the monodomain model should be used in place of the Eikonal model.Mathematics, AppliedMathematicscardiac electromechanicseikonal modelpv loopsnumerical simulationshearttissuecontractionmonodomainexcitationalgorithmpropagationmyocardiumactivationgenerationA fast cardiac electromechanics model coupling the Eikonal and the nonlinear mechanics equationstext::journal::journal article::research article
