Abstract :
Recent studies showed that spiral waves could be involved in cardiac fibrillation. Changing the dynamics of spiral waves and stoping them by electric stimulations provide a potential way of defibrillation. However, electric stimulation could bring some serious problems to patient as well. So, our aim in this paper is to determine an optimal stimulation mode, such as the number of required stimulated sites and parameters in order to suppress spiral waves in a cardiac tissue.
