  • Title: Idiopathic polymorphic ventricular tachycardia with normal QT interval in a structurally normal heart.
    Author: Mechleb BK, Haddadin TZ, Iskandar SB, Abboud LN, Fahrig SA.
    Journal: Pacing Clin Electrophysiol; 2006 Jul; 29(7):791-6. PubMed ID: 16884519.
    Abstract:
    Polymorphic ventricular tachycardia (PVT) is a life-threatening arrhythmia that is typically related to long QT syndrome, organic heart disease, electrolyte abnormalities, cardiotoxic drugs, or adrenergic stimulation. A review of the literature reveals that PVT with normal QT interval and without underlying cause is quite rare. We report a case of idiopathic spontaneous PVT with structurally normal heart and without electrolyte abnormalities, drug reactions, or evidence of catecholamine induced arrhythmia. We also review the literature on the electrocardiographic characteristics and management of idiopathic PVT.
