[Dynamics of the excitable media with two interacting pacemakers].
A general model of the nonlinear interaction of two impulse systems was developed, which describes some types of cardiac arrhythmias. Phase locking phenomena were studied with consideration for refractoriness time. The phenomena of tongue splitting and the overlapping of the major synchronization regions were revealed. The results obtained make it possible to predict the behavior of excitable systems with two pacemakers depending on the type and intensity of their interaction and on the initial phase difference.
