Most naturally occurring excitable media exhibit vortices in the form of spirals rotating around circular cores. Here we demonstrate that quite another type of vortices - vortices whose cores resemble a long line - may result from decreasing a small parameter in the different mathematical models of excitable media (general reaction-diffusion model, Fitz-Hugh-Nagumo equations, Beeler-Reuter model of cardiac tissue, Wiener axiomatic model, and cellular automata model).
