Figure 10.

(A) Snapshot of voltage on a strip of tissue of size (l_x = 40, l_y = 200) paced at the left edge. The image shown is at the time indicated during the 18th beat. (B) The voltage time course at points 1 (l_x = 30, l_y = 180) and 2 (l_x = 30, l_y = 20) is shown. Vertical dashed line corresponds to the time of snapshot shown in (A). (C) CV as a function of q measured on a cable of 200 cells is shown. CV is measured for the last 15 beats after pacing for 50 beats. To see this figure in color, go online.
