Figure 3A, B, C. Local abnormal electrocardiogram of Periaortc VT from RVOT (Case 2)
Figure Legend: Ablation catheter was positioned in the RV/LV septum below the artificial aortic valve from the right ventricular outflow tract (A/B). Intracardiac electrocardiogram revealed fragmented potentials in low voltage zones (C: white allow), and we also got a good pace map for the target periaortic VT in the same position.
Abbreviations: ABL, ablation; CS, coronary sinus; LBBB, left bundle branch block; LGE, late gadolinium enhancement; LV, left ventricle; RV, right ventricle; RVOT, right ventricular outflow tract; SR, sinus rhythm; VT, ventricular tachycardia
