We propose a finite element approximation to solve the coupling between the propagation of electrical potential and large deformations of the cardiac tissue, based on the active strain assumption. A new phenomenological model for the mechanical activation is introduced and various numerical tests performed with a parallel finite element code illustrate that the proposed method can capture some important features of the excitation-contraction mechanism.
