Abstract
A two-dimensional model of anisotropic cardiac tissue using a rectangular grid of elements and the Beeler-Reuter formulation is used. Dead cell barrier effects on the plane wave propagation were studied to determine possible conduction blockage mechanisms. It is shown that abrupt increases in healthy tissue width can produce blockage and that dead cell strips corresponding to dead or collagenous tissue placed perpendicularly to the wavefront direction can facilitate propagation by creating tortuous pathways. Plane wave traveling in the transverse direction was also studied and it is shown that a one-cell opening is enough for the wave to propagate.
