Abstract
In real electrophysiological experiments, irregularities in the extracellul ar excitation spread are believed to depend on cardiac tissue microstructur e. An electronic hardware model was developed to analyze this dependence by placing some inhomogeneities (slow propagation areas) in the medium. The p osition of such inhomogeneities is correlated with abnormal delays and irre gularities measured in signal propagation. [S1063-651X(99)10505-1].
