We detail findings in a patient with incessant idiopathic left ventricular tachycardia (ILVT), induced cardiomyopathy, and an “electrical storm” consisting of recurrent polymorphic ventricular tachycardia (PVT). Catheter ablation not only eradicated the ILVT, but also additionally suppressed recurrent PVT. These findings suggest that the recurrent PVT storm in this patient related to long‐standing tachycardia‐induced cardiac electrical remodeling that led to QT prolongation.
