Abstract
A 3D cellular automata model of the entire heart was used for modelling the spread of excitation and repolarization in the heart. By modelling ventricular pacing and premature stimuli the inducibility of bundle branch re-entry was investigated. Under normal conditions bundle branch re-entry of type A and B were induced. A reduction of conduction velocity in the bundle branches resulted in multiple re-entrant echo beats as well as a wider zone of re-entrant activation
