Septal ventricular tachycardia with alternating LBBB-RBBB morphology in isolated ventricular noncompaction.
Knowledge on ventricular tachycardia (VT) in isolated ventricular noncompaction (IVNC) is limited. We report on a patient with IVNC who presented with cardiogenic shock due to an incessant drug-resistant VT that was cured by radiofrequency ablation. The VT had characteristics of a deep septal focal arrhythmia, which was distinctive by ablation-induced alternation of the rightward and leftward exits, and was difficult to ablate from either side of the ventricular septum.
