Case 2-4
Similarly, the PVC characteristics in cases 2-4 are shown in the Table and the electrophysiological features in Figures 2-4 including the PVC morphologies (Figures 2A-4A), presystolic potential during the PVC, and late potentials during SR at the successful ablation sites (Figures 2B-4B), and coherent vector activation maps annotating the presystolic potential during the PVC (Figures 2C-4C) and late potentials during SR (Figures 2D-4D). Bidirectional conduction of the preferential pathways was seen in all cases.
In case 4, 2 different PVCs were targeted: 1 from the PA and the other from the LCC. Bidirectional conduction of the preferential pathway was suggested in both PVCs.
