Spiral wave trajectories in the three-variable Fenton-Karma model [63] can be reproduced with ease by changing model parameters interactively. Panels A to D were obtained by initiating a spiral wave starting with parameter “set 1” in reference [63]. From A to D, the time constant τd was gradually decreased and set to 0.42, 0.40, 0.389, and 0.38, to obtain circular, epicycloidal, cycloidal, and hypocylcoidal trajectories, respectively. The hypermeandering trajectory in panel E was obtained by using parameter “set 10” from the reference [63] and the linear trajectory in panel F was obtained using parameter “set 2” of the same reference.
