Algorithms for the intraoperative modeling of the dynamics of atrial excitation

The problem is studied of the modeling of atrial excitation in clinical conditions. The basic model requirements and the existing methods are considered for modeling the excitation dynamics of the contractile myocardium. The cellular automaton theory serves as the basis of a model. The calculations are carried out on a rectangular grid. For each pair of the cellular automaton elements, the time delay of the excitation transfer is computed. Such an approach allows us to adapt the model to the particular data obtained by electrophysiological tests.
