Propagation of a planar wave on a tissue of 170 × 170 cells. The tissue is paced by stimulating a vertical strip of size 10 × 170 on the left edge of the square tissue. (A) Voltage snapshots at the indicated times after the 20th paced beat for cell model with q = 0.9 are shown. (B) Voltage snapshots at the indicated times after the 16th paced beat for q = 0.3 are shown. To see this figure in color, go online.
