Figure 1 (A) Twelve-lead ECG in a 17-year-old male with syncope and palpitations who had successful ablation from the left sinus of Valsalva. Note the nonsustained ventricular tachycardia (VT) had left bundle branch block, inferior axis morphology with transition in V3 and rS pattern in lead I. (B) Identical pace mapping from the successful site above left coronary cusp is shown. The left side of the panel shows spontaneous nonsustained VT and the right-side panel shows the pace mapping at the successful site. The recordings V2 and V3 were obtained from sites lateral to the standard position because of placement of a defibrillator patch in the lower chest region.
