Abstract:
We present a simple model, describing the propagation of a travelling signal in a media that is intended to model phenomena in cardiac tissue. The model is a caricature designed to examine some characteristics of a propagating medium that can support spontaneous and non-stimulated fibrillation behaviour. The model consists of a large number of weakly interacting components, each of which operates according to a simplified set of rules. Specifically it is a form of cellular automaton, with the introduction of probabilistic nature in terms of a random refractory period.
