The distribution of the DFs, rotors and LVAs in the LA after the PVI
A. The %NPs≧50% and high-DF sites≧7Hz were frequently identified in the inferior and anterior regions of the LA, respectively. B. LVAs were frequently identified in the septal, anterior, and posterior regions of the LA. C. High-DF sites ≧7Hz overlapping with LVAs were frequently identified in the septal, roof, and inferior regions of the LA and %NPs≧50% overlapping with LVAs in the anterior and septal regions.
