Abstract

Description

On the basis of a quite realistic ionic Fenton--Karma model of the cardiac tissue we consider the problem of defibrillation by a local weak forcing. In contrast to other systems, this model accurately reproduces the most essential mesoscopic properties of the cardiac activity. It is shown that suppression of spiral--wave turbulent dynamics in the heart tissue may be realized by a low-voltage local non-feedback electrical stimulation of monophasic and biphasic shapes. After stabilization the medium goes to a spatially homogeneous steady state.
