Fig. 2From: Spatial correction improves accuracy of catheter positioning during ablation of premature ventricular contractions: differences between ventricular outflow tracts and other localizationsInfluence of PVC-origin on spatial displacement. Scatter plot showing spatial displacement of mapping points depending on the area of PVC-origin. The median spatial displacement was significantly lower in maps recorded for PVCs originating in the ventricular outflow tracts (p = 0.045). Standard deviation was comparable in both groupsBack to article page
