The activation map and voltage map for 2 patients. (A1, A2) The earliest point at the posterior septal side of the RVOT (PA, RAO 30). (A3) The red dot shows the successful ablation site at the earliest point. (A4) An electroanatomic voltage map of the RVOT obtained using the CARTO system (PA). The areas outlined in red indicate the low‐voltage zone (<0.5 mV), those in green indicate the transitional‐voltage zone (0.5–1.5 mV), and those in purple indicate the high‐voltage zone (>1.5 mV). Compared with (A1) and (A3), the earliest point and successful ablation site were at the transitional‐voltage zone. (B1, B2) The earliest points at the anterior septal side of the RVOT (LL, PA). Similar to the observations in (A1) and (A3), the earliest point and successful ablation site were also at the transitional‐voltage zone (B3). Abbreviations: LL, left lateral; PA, posteroanterior; RAO, right anterior oblique; RVOT, right ventricular outflow tract.
