Abstract

The simulation of action potential propagation on cardiac tissuesis a very intensive process, both in terms of memory and computationalload. Complex ionic models such as the Luo-Rudy Phase 2, along withthe ever-increasing need to simulate larger tissues during longertime, require the use of high performance parallelization strategies.This paper presents a complete parallel computing system for thesimulation of action potential propagation in a two-dimensional monodomaincardiac tissue using a cost-effective cluster of PCs. High performancecomputing techniques have reduced the simulation time by a factorof nearly the number of processors, reaching a 93% of efficiencywith ten processors. In addition, stable numerical ODE integrationmethods allow the use of a larger timestep, reducing the overallsimulation time up to a factor of 8.
