Reduced order model in cardiac electrophysiology with approximated Lax pairs

A reduced-order method based on Approximated Lax Pairs (ALP) is applied to the integration of electrophysiology models. These are often high-dimensional parametric equation systems, challenging from a model reduction standpoint. The method is tested on two and three dimensional test-cases, of increasing complexity. The solutions are compared to the ones obtained by a finite element. The reducedorder simulation of pseudo-electrocardiograms based on ALP is proposed in the last part.
