Hands-on help Torsades de pointes.

Torsades de pointes, a French term that literally means "twisting of the points," is a lethal form of ventricular tachycardia named for its hallmark feature: polymorphic QRS complexes that appear to twist around the isoelectric line. Without treatment, few patients survive Torsades de pointes (TdP) once it develops. The key to preventing sudden cardiac death lies in early detection of warning signs.
