We present an electromechanical model of myocardium tissue coupling a modified FitzHugh–Nagumo type system,describing the electrical activity of the excitable media, with finite elasticity, endowed with the capability of describingmuscle contractions. The high degree of deformability of the medium makes it mandatory to set the diffusion process in amoving domain, thereby producing a direct influence of the deformation on the electrical activity. Various mechanoelectriceffects concerning the propagation of cylindrical waves, the rotating spiral waves, and the spiral breakups arediscussed.

Abstract
We present an electromechanical model of myocardium tissue coupling a modified FitzHugh–Nagumo type system,describing the electrical activity of the excitable media, with finite elasticity, endowed with the capability of describingmuscle contractions. The high degree of deformability of the medium makes it mandatory to set the diffusion process in amoving domain, thereby producing a direct influence of the deformation on the electrical activity. Various mechanoelectriceffects concerning the propagation of cylindrical waves, the rotating spiral waves, and the spiral breakups arediscussed.File in questo prodotto:
