Popis:	A change in the dynamics of a solitary spiral wave in a two-dimensional lattice of model elements of the FitzHugh-Nagumo type with diffusion coupling upon the introduction of a topological defect with constant potential is considered. It is shown that the scale of spatiotemporal structures formed in the system can exhibit significant changes depending on the defect potential. Features of the interaction of a spiral wave with defects in the models of excitable and autooscillatory media are considered.
