Summary:
A serious cardiac arrhythmia is well known as a main cause of cardiac sudden death. The arrhythmia is considered to be induced by spiral waves and spatio-temporal chaos in the cardiac muscle. The muscle has the characteristic feature of excitable media. This paper proposes a feedback control method for eliminating spiral waves in a cellular automata model of excitable media. The method can eliminate spiral waves by a low-amplitude pulse train. Its control performance is investigated by numerical simulations.
