Figure legends
Figure 1. Twelve-lead electrocardiogram of a PVC recorded
during the procedure (A) . Intracardiac electrograms at the
successful ablation site. A presystolic potential during the PVC and
late potential during SR are recorded by the ablation catheter. The late
potential during SR was eliminated after the successful ablation(B) . Coherent vector activation maps annotating the presystolic
potentials during the PVC (C) and late potentials during SR(D) . The ablation catheter at the successful ablation site is
shown in the figure.
SR, sinus rhythm; PVC, premature ventricular contraction; LCC, left
coronary cusp; RCC, right coronary cusp; ABL, ablation.
