Figure 4. Intercellular calcium wave triggers depolarization wave; Calcium-Depolarization-Calcium wave.
In the upper panel we see wave traversing 10 cells. The wave is a combination of calcium wave and intracellular depolarization wave; a slow calcium wave is overtaken by a fast depolarization wave. This is repeated for all the cells and results in a wave traveling at about 0.65 mm/s. In the simulation the gap-junctional electrical conductivity is reduced to 0.01% (of the default value given in Table 1) and GK1 is reduced to 30%.
