From: Propagation velocity profile in a cross-section of a cardiac muscle bundle from PSpice simulation
Graphs of the cross-sectional profile through a small-diameter cardiac bundle of the propagation velocities for different numbers of gj-channels: 0 (A), 10 (B) and 100 (C). The longitudinal resistance of the interstitial fluid between the 20 parallel chains (Rol2) was elevated 10-fold to 2000 KΩ (from the standard 200 KΩ). The main difference in the profiles, compared to when Rol2 was 200 KΩ (Fig. 4), is the widening and dimpling of the bell in panel A.
