Cardiac wave dynamics around the mother rotor.
Maps of voltage, PS, DF, ShEn, and CFAE under the control condition (A), at which ion current conductance values are the Courtemanche et al.  model values, and under AF condition (B), at which ion current conductance values are adjusted as shown in Table 1. In the DF map of the AF condition, the two highest DF areas are circled. Action potential curves are also shown for both control and AF conditions (C). D. DF areas (blue) are completely covered by the rotor tip trajectories (red). E. The trajectory of the mother rotor tip (black) is overlaid on the DF map. F. The trajectory of the mother rotor tip (black) is overlaid on the ShEn map. G. The trajectory of the mother rotor (black) tip is overlaid on the CFAE map.
