| Abstract(in English) | Partial differential equations of 2D cardiac tissue, based on Hodgkin-Huxley type model, require large amounts of computing time. In this study, a new hybrid integration method of node decimation and adaptive time step control was examined. In computer simulations for 2D normal cardiac model, the computing speed of the hybrid method is 9 times faster than the speed of conventional differential calculus, and 1.4 times faster than the speed of the node decimation method. On the other hand, the difference of calculated action potential waveforms between the hybrid and the conventional method was almost small. Therefore, the proposed hybrid method provides high efficiency and accuracy for computing the propagating action potential. |
