A: Induction of clinical ventricular tachycardia (VT) with right bundle, right superior axis, which was localized to the anterior and inferior septum. B: Cardiac magnetic resonance imaging demonstrates severe global left ventricular systolic dysfunction with focal partial-thickness subendocardial late gadolinium enhancement in the anterior, anteroseptal, and anterolateral waves, corresponding to region where critical isthmus was mapping in VT, along with fractioned potentials and deceleration zone with right ventricular pacing wavefront.
