  • Title: The perfect storm: Torsades de Pointes in a child with leukemia.
    Author: Bagatell R, Hainstock M, Lowe MC, Barber BJ, Samson RA.
    Journal: Pediatr Blood Cancer; 2007 Dec; 49(7):996-9. PubMed ID: 16333840.
    Abstract:
    Torsades de Pointes (TdP) is a life-threatening ventricular arrhythmia that can be associated with metabolic abnormalities, exposure to arrhythmogenic medications, and congenital long-QT syndrome. This report describes a patient with ALL and multiple complications of therapy who developed TdP. The patient had no evidence of congenital long-QT syndrome, but a constellation of factors appears to have led to QT prolongation, ventricular ectopy, and TdP. Although the patient suffered cardiac arrest, rapid recognition of TdP and prompt defibrillation resulted in an excellent outcome.
