Previously carried out simulation of myocardial exciting propagation was using lattice structure models composed of square units or hexagonal units. These models were planar, and problematic in that the front of the excitement-propagating wave form became polygonal rather than circular. The problem can not be resolved even by increased unit numbers. To solve this problem, we created an amorphous model. As a result, nearly circular exciting wave fronts were successfully obtained in the amorphous model. In addition, when multiple (3) stimuli were applied to the two kinds of types of model simultaneously, in lattice structured models, continued shifting of the three stimuli locations by 90 degrees, respectively provoked noticeable differences in the residual form of exciting waves, but in the amorphous model, no such illogical phenomenon were noted. Furthermore, when an area with abnormal excitement propagation was established in a region of the models simulated propagation bring about different outcome between the lattice model and the amorphous model. Reentry mechanism might be shown on the amorphous model but not be able to so on the previous lattice model. Further trial is undergoing. Based on the foregoing information, we confirmed the utility of an amorphous model.
