Example of a successful ablation of a premature ventricular contraction (PVC) originating from the inferoseptal portion of the basal right ventricular region.

<p>(A) The surface ECG characteristic. (B) The local ventricular activation time recorded at the successful ablation site that preceded the onset of the QRS complex was 32 ms. (C) Pace map at the ablation site. (D) The fluoroscopic position of the ablation catheter site. ABL, ablation catheter; RAO, right anterior oblique projection; LAO, left anterior oblique projection.
