sionnach commented on the word torsades de points
A cardiac arrhythmia, usually stemming from prolongation of the QT-interval on an electrocardiogram. In severe instances, it can lead to blackouts, and even death. A common cause is an adverse reaction to certain classes of drugs, particularly those that prolong the QT-interval by blocking potassium channels. Also common in individuals with genetic mutations in genes that control expression of sodium or potassium channels and is a frequent cause of sudden death in these individuals.
