[The rotation of autowaves as a result of their penetration through a system of unexcitable obstacles. A mechanism of arrhythmias associated with aging].
The dependence of the frequency of occurrence of excitation vortices rotating around unexcitable obstacles on the size and the number of the obstacles and also on the medium excitation threshold was studied. It was shown that the vortex formation takes place in a wide range of the model parameter values. The assumption was formulated that the mechanism of formation of excitation vortices under study underlies the increase in the heart arrhythmias associated with aging.
