Figure 5.
Relationship between induction of AF and LA body area, calculated wavelength and effective conducting size. A, LA body area is plotted on the x‐axis and calculated wavelength (see text) on the y‐axis for all patients in the study. B, Isolines represent LAECS. Patients with paroxysmal AF who were both AF inducible (D) and AF noninducible (C) localized around the 2 to 4 cm LAECS region (shaded). Patients with persistent AF who were noninducible occupied a larger range of effective conducting size from 1.3 to 10 cm (E). Patients with persistent AF who were AF inducible largely fell within the >4 cm range for LAECS. AF, atrial fibrillation; LA, left atrium; LAECS , LA effective conducting size; PAF, paroxysmal AF; PsAF, persistent AF
