Ablation of a slow-conducting isthmus can terminate spiral wave pairs. A. The hatched zones are non-conduction regions that sandwich an area of slow conduction, modeled as reduced cell-to-cell coupling that could biologically represent remodeled atrial tissue or patchy fibrosis. The mismatch in CV in this channel and the surrounding tissue creates a figure-of-eight reentry pattern, indicated by the green arrows in D. Domain size 5cmx5cm, D varies linearly in the isthmus from D=0.0002 cm2/ms (left-side) to D=0.00005 cm2/ms (right-side). Scalebar: 1cm.
