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

Figure 6

A small filament anchored to the right ventricular apex. (a) Surface potential at ms, with an apex-to-base view. The surface phase singularity persists in this neighbourhood for 270 ms; the blue line plots its trajectory. (c) The spatial distribution of phase at ms (values ranging from to ). The PS, identified by the arrow, is clearly visible. (d) Snapshots of the small stable transmural filament that corresponds to this phase singularity (movie also provided in supplementary material).
