Severe Torsades de Pointes with acquired QT prolongation. Torsades de pointes (TdP) is a fatal polymorphic ventricular tachycardia in association with congenital or acquired QT prolongation. Concomitant electrolyte disturbances and drugs potentiate the development of TdP. We describe a severe case of refractory TdP in the setting of methadone, cocaine, hypokalemia and hypomagnesemia. The successful treatment was achieved with the administration of magnesium, isoproterenol, and electrolyte replacement.
