| Popis: |
On the basis of a modified FitzHugh-Nagumo system and a quite realistic ionic Fenton-Karma model describing the wave propagation in cardiac tissue we resolve the problem of suppressing the fibrillative activity of the heart by a low-voltage local electrical forcing. Such a low-energy defibrillation has a great advantage in comparison with other widespread methods since it, in particular, does not require the knowledge of the frequency of re-entrant waves. All the rotating waves are suppressed almost simultaneously and the initial cardiac rhythm can be reestablished because after stabilization the medium goes to a spatially homogeneous steady state. |
