Abstract. In computer simulations, we found a new type of spiral wave drift in ΰ homogeneous two-dimensional excitable medium, namely, a circular drift of the spiral wave with decrease of the drift velocity right up to its total cessation. We have investigated certain quantitative characteristics of the new spiral wave behavior. As a result, we have demonstrated that the new spiral wave behavior essentially differs from the types of its behavior that was known before. This discovery can improve comprehension of mechanisms of some potentially life-threatening cardiac arrhythmias.

Key words: excitable media, spiral waves, mathematical modeling, cardiac arrhythmia.
