system of two reaction-diffusion equations, while the
Monodomain model consists of one reaction-diffusion
equation. Both models are coupled with the phase I
Luo-Rudy membrane model describing the ionic currents.
Simulations of excitation and repolarization sequences
on myocardial slabs of different sizes show how the
distribution of the action potential durations (APD) is
influenced by both the anisotropic electrical
conduction and the fiber rotation. This influence
occurs in spite of the homogeneous intrinsic properties
of the cell membrane. The APD dispersion patterns are
closely correlated to the anisotropic curvature of the
excitation wavefront.",
