Secrets to the success of the Rush--Larsen method

Cardiac electrophysiology can be modeled by the bidomain equations, a multi-scale reaction-diffusion system of nonlinear ordinary differential equations describing the ionic currents at the cellular scale coupled with a set of parabolic partial differential equations describing the propagation of the electrical activity at the tissue scale. To produce clinically useful data, billions of variables must be evolved. In this presentation, I discuss the Rush--Larsen method, arguably the most effective time-integration method for the ionic currents in the bidomain equations. I reveal the secrets of the method's success and suggest a generalization that can be even more effective.
