Summary:
Spiral waves and spatio-temporal chaos are the main causes of a serious cardiac arrhythmia. The cardiac muscle has characteristic features of excitable media. It is well known that the fibrosis of myocardium, sets of non-excitable cells, is strongly correlated with an incidence of serious arrhythmias. The present paper examines the suppression of spiral waves and spatio-temporal chaos in excitable media with fibrosis. The boundary periodic pacing is applied to the excitable media. The influence of non-excitable cells on the suppression performance is investigated on numerical simulations. These numerical investigations suggest that the angular frequency of the boundary periodic pacing should be low for the high fibrosis ratio.
