Filament Dynamics during Simulated Ventricular Fibrillation in a High-Resolution Rabbit Heart

Figure 4

Close-up of intramural filament dynamics. Initially (ms), a single long convoluted epi-to-endo filament is present. It then breaks up into a shorter epi-to-endo filament and a ring (ms; note that the ring is partially obscured). The ring begins to shrink (ms) but then reconnects to the epi-to-endo filament (ms).
