ABSTRACT A prolonged QT interval can be caused by medications, electrolyte abnormalities, or long QT syndrome, a genetic mutation that prolongs the action potential. Torsades de pointes is a potentially fatal polymorphic VT most often associated with prolonged QT interval. This article focuses on recognizing and treating drug-induced torsades de pointes.
