Modeling Heart Pacemaker Tissue by a Network of Stochastic Oscillatory Cellular Automata

摘要

Computations performed by a system of cyclic cellular automata, designed to model the principal organization rules known for the tissue of the first cardiac pacemaker - the sinus node, are investigated in terms of Kuramoto order parameters of synchronization. We show that such description provides consistent quantification of stationary states in the model. Finally, the model is used to give possible explanations for changes observed in the sinus node rhythmicity caused by age.
