We found a new type of spiral wave behavior in a homogeneous two-dimensional autowave medium. At that regime, the spiral wave tip motion transforms from two-periodic meander into one-periodic circular rotation due to spontaneous deceleration of spiral wave drift. This discovery might be useful for insight into the nature of different phenomena, and, in particular, for comprehension of some potentially life-threatening cardiac arrhythmias.
