Points at which different types of waves are observed in the G_CaL-G_Kr parameter space.

Enlarged versions of two of the stability diagrams of Fig 3 (PCL = 3500ms for the ORd model and PCL = 500ms for the TP06 model) showing the types of waves, which occur at different values in the G_CaL-G_Kr plane, by the following symbols: yellow and magenta circles (phase waves); yellow-filled triangles (Ca-mediated waves); open squares (Na-Ca-mediated waves); yellow-filled squares (waves mediated by I_Na).
