The University of Arizona Center for Education and Research on Therapeutics provides a handy list of medications associated with Torsades de Pointes, a ventricular tachyarrhythmia often seen in the setting of hypokalemia, hypomagnesemia, hypocalcemia, diarrhea, or alcoholism.
Torsades has the dangerous potential for degeneration into ventricular fibrillation and is treated with magnesium sulfate infusion and, if necessary, defibrillation. Removal of predisposing drugs is essential for long-term protection. Refer to Arizona’s drug lists when you notice QT prolongation on EKG.
