Variability in pulmonary vein electrophysiology and fibrosis determines arrhythmia susceptibility and dynamics

Fig 2

Phase singularity trajectories depend on both PV properties and fibrosis distribution.

Trajectories over time for control PV properties (CV: 0.67m/s, APD: 181ms; first two columns, anteroposterior and posteroanterior views); PVs with slow CV (CV: 0.51m/s; middle column); and PVs with short APD and slow CV (CV: 0.51m/s, APD: 120ms; right column). Rows indicate degree of fibrosis, with no fibrosis (control, top row); a distribution averaged over paroxysmal patients (middle row); a distribution averaged over persistent patients (bottom row). Colours indicate the time at which a PS was detected at a site.
