Supplementary Movie 3 (tp06.mp4): Traveling Wave Evolution in the nine variable ten Tusscher-Panfilov (TP06) Model

The vertical and horizontal scales for the traveling wave (bottom left) have been normalized. The current state is indicated by a blue marker on the dispersion curve, where pink squares denote saddle-node bifurcations and green dots denote Hopf bifurcations.

As the parameter varies across the six distinct solution branches, the fast wave undergoes profound morphological transitions, developing into diverse unstable slow waves that include broad depolarized plateaus, early afterdepolarization (EAD)-like structures, and complex multi-peak waveforms. Simultaneously, the spectrum panel visualizes the highly complex linear stability dynamics, showing cascades of destabilizing Hopf bifurcations as well as a brief window of restabilization on the fast wave branch.
