A cellular automaton computer model for the study of magnetic detection of cardiac tissue activation during atrial flutter

A discrete cellular automaton computer model was applied to simulate the excitation wave propagation characteristic of the fundamental mechanisms of atrial flutter arrhythmia. The magnetic field produced by the different possibilities of simulated tissue activation associated to the arrhythmia has been calculated. After recording the signal as a function of time, isoamplitude maps were configured. The different computational images obtained could distinguish the various specific configurations of tissue activation.
