Abstract

Large scale modelling of two-dimensional cardiac tissue using parallel methods N. Maglaveras", K. Margaritis\ J. de Bakker^ F.J.L. van Capelle^, M. AHessie^, M. Strintzis" & C. Pappas* "Aristotelian University, Thessaloniki, Macedonia, Greece Greece <* University of Limburg, Maastricht, Holland ABSTRACT Finite difference and iterative methods are used to simulate two-dimensional impulse propagation in cardiac tissue. The model used takes explicitly into account the effects of cytoplasmic and junctional resistances. An initial parallel approach for the implementation of the iterative methods (Gauss-Seidel in our case) based on the systolic array method is presented. The number of iterations needed for convergence of the iterative methods at each time step is examined in conjunction with changes in the spatial distribution of the electrophysiologic parameters such as coupling resistance. Electrograms and propagating action potentials (PAP) are calculated
