Modeling ventricular excitation: axial and orthotropic anisotropy effects on wavefronts and potentials

By applying the eikonal approximation to the bidomain model of the cardiac tissue we investigate the influence of the axially isotropic and orthotropic conductivity tensors on the propagation of the excitation wavefronts and on the associated potential distribution and electrograms.
