Fig. 3From: Atrial fibrillation source area probability mapping using electrogram patterns of multipole cathetersa Each bar represents a normalized trajectory length present in each probability area. b Difference between the calculated principal wave direction (PWD) angle and the true angle of the AF source. c Average iterations until a source detection. The values were averaged over focal and reentry cases (simulation cases of Fig. 1a, b). HP high probabilityBack to article page
