Cellular automation model of ventricular conduction.

A computer simulation of ventricular conduction is presented with a discrete element ventricular conduction model. The model is shown to be capable of demonstrating normal ventricular rhythm, including QRS and T-waves, plus a variety of rhythm disturbances including missed beats, electrical alternans and self-sustaining instability with arrhythmias. The morphology of the range of alternans produced bears a strong resemblance to certain clinically recognised arrhythmias.
