Coupled Eikonal problems to model cardiac reentries in Purkinje network and myocardium

Samuele Brunati, Michele Bucelli, Roberto Piersanti +2

We propose a novel partitioned scheme based on Eikonal equations to model the coupled propagation of the electrical signal in the His-Purkinje system and in the myocardium for card…
