摘要

整个心脏的三维元胞自动机模型用于模拟心脏内兴奋和复极化的扩散。通过模拟心室起搏和过早刺激，研究了束支再入的诱导性。在正常条件下，诱导A型和B型束枝再入。束状分支传导速度的降低导致多次重入回声搏动以及更宽的重入激活区。

Computer simulation of bundle branch re-entry in a 3D cellular automata model of the heart

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.
