Modulation of atrial fibrillation reentrant dynamics by intersubject variability in action potential phenotype. Interpolated maps show dorsal views of the atria for dominant frequency (DF), organization index (OI), regularity index (RI), and coupling index (CP) between adjacent electrogram (thick white lines represent CP > 0.9, thin solid lines represent 0.75 ≤ CP < 0.9, and soft gray lines represent 0.6 ≤ CP < 0.75. CP < 0.6 is represented by absence of lines) for short and long APD₉₀, APD₅₀, and APD₂₀ virtual phenotypes.
