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.

Description

An example of Torsade de Pointes. A normal sinus beat is followed by a ventricular extrasystole (shortly after the sinus beat), the compensatory pause results in a longer interval to the next beat. This longer beat therefore has a longer QT interval. The next beat follows shortly 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.
