Conduction velocity (CV) dependence on cell size and Na+ channel density in mutant tissue. CV is shown as a function of cell size (S) for different values of Na+ channel density (ρNa) for 10% (left column), 50% (middle column), and 90% (right column) Na+ channel ID localization (IDNa) for (A) weak (fgap = 4%) and (B) strong (fgap = 100%) gap junctional (GJ) coupling. CV for wild-type (WT) is shown for 100% ρNa for comparison (black lines). Parameters: BCL = 1000 ms, cleft width w = 40 nm.
