From: Propagation velocity profile in a cross-section of a cardiac muscle bundle from PSpice simulation
Action potential (AP) traces recorded intracellularly in cells 1, 5, and 10 of each of the 20 parallel chains of the cardiac bundle. The order of firing for panel A (cells 5 and 10 of each chain) is given by the inset table at the lower right of the figure. A Zero gj-channels. The first visible trace consists of the superimposition of the 20 AP traces recorded from cell #1 of all 20 chains. B: 100 gj-channels. Each of the three traces visible (cells # 1, 5 and 10, respectively) consists of the superimposition of the 20 APs of the 20 parallel chains.
