-| example = An example of Torsade de Pointes. A normal sinus beat is followed by a ventricular extrasystole ('''short'''ly after the sinus beat), the compensatory pause results in a '''long'''er interval to the next beat. This longer beat therefore has a longer [[Conduction|QT interval]]. The next beat follows '''short'''ly therafter, withing the QT interval. Not all ventricular cells have been repolarized by that time and a ventricular arrhythmia results. This short-long-short sequence is typical for Torsades de pointes.[[Image:Rhythm_torsade.png|250px|Initiation of Torsade de Pointes (TdP) by a short-long-short sequence]]

 There has been much debate in the ''Circulation'' journal among French and American scientist whether one should write ''Torsades de Pointes'' or ''Torsade de Pointes''. As for now ''Torsade'' is prefered (unless one sees rotations around more than one axis in one episode), but both forms are used in similar frequency.<cite>Moise</cite>
