Abstract (in Japanese) (See Japanese page) 
(in English) Cardiac cells generate the action potential, which has relatively long absolute refractory period, so-called, the plateau phase, and, as such, show an acceleration phenomenon, or an increase of the frequency, driven by the low energy consumption when the cells are coupling. In this study, we investigated such a “high-efficiency acceleration phenomenon” on the 40-cell coupling of Noble equation, which is one of the Hodgkin-Huxley type neuron models, using the software insilicoIDE. We were simulated about influences of the number of couplings of cardiac cell models (from 2 to 12 models). As a result, the “high-efficiency acceleration phenomenon” was observed after coupling. Furthermore, it was suggested that there was the optimal number of couplings which gives the influence to the “high-efficiency acceleration phenomenon,” and the optical number was nearly equal to that observed in the actual cardiac tissue.
