It appears that the QT-prolongation is a dose-related effect and that in low doses, droperidol is not a significant risk. Torsades de pointes or torsades is a French term that literally means twisting of the points. It refers to a specific variety of ventricular tachycardia and its name is derived from a maneuver in ballet. ...
