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.

QT Prolongation Is a Poor Predictor of Proarrhythmia Liability: Beyond QT Prolongation!
2011Prolongation of ventricular repolarization, reflected by QT prolongation in the ECG, was introduced as a major antiarrhythmic mechanism, but soon became a surrogate for Torsade de Pointes (TdP) instead. However, drugs that prolong the QT interval range from potently torsadogenic activity to no proarrhythmic action and even antiarrhythmic effects. While
