Spatial distribution of APD during from pacing at 500 ms intervals in each variant of the 60 × 60 mm virtual tissue. (a) Effect of changing spatial scale, with ΔgKmax fixed at 0.003 mS mm^-2, and diffusion coefficient fixed at 0.1 mm² ms^-1. (b) Effect of changing ΔgKmax, with spatial scale fixed at 10 mm, and diffusion coefficient fixed at 0.1 mm² ms^-1. (c) Effect of changing strength of cell-to-cell coupling by changing the diffusion coefficient, with spatial scale fixed at 10 mm, and ΔgKmax fixed at 0.003 mS mm^-2.
