Pseudocolor plots showing Vm on the surfaces of our 3D domain illustrating the wave patterns of the three wave-types in ORd and TP06 models.

The leftmost set of figures represents the Na-Ca-mediated type; the middle represents the Ca-mediated type; the rightmost represents the phase waves. The parameter sets are as follows. Na-Ca-mediated: (ORd) GCaL = 4 and GKr = 0.37; (TP06)GCaL = 3 and GKr = 0. Ca-mediated: (ORd) GCaL = 4 and GKr = 0.275; (TP06)GCaL = 4 and GKr = 0. Phase waves: (ORd) GCaL = 4 and GKr = 0.2; (TP06) GCaL = 6.8 and GKr = 0.1.
