Een Torsade de Pointes wordt gekenmerkt door een typisch ECG-patroon waarbij het QRS-complex als een golfbeweging pendelt om de iso-elektrische basislijn, waarbij de amplitude van het QRS-complex slag na slag lager wordt, vervolgens omslaat naar de andere zijde van de basislijn, slag na slag weer groter wordt tot de maximale uitslag en dan weer kleiner, als een sinusoïde golfbeweging. Torsades de pointes (o simplemente torsades) es un término francés que literalmente significa puntas retorcidas.Lo describió François Dessertenne en 1966 y se refiere a una taquicardia ventricular específica que muestra características claramente reconocibles en el electrocardiograma (ECG). Torsades de pointes is a specific form of polymorphic ventricular tachycardia in patients with a long QT interval. It is characterized by rapid, irregular QRS complexes, which appear to be twisting around the electrocardiogram (ECG) baseline.

Résultat, le coeur bat à 250 par minutes, ce qu'il fait qu'il n'a plus de temps de se remplir : la pompe cardiaque bat alors dans le vide. Cela équivaut à un arrêt cardiaque, donc gravissime.

Jervell and Lange-Nielsen syndrome (JLNS) is characterized by congenital profound bilateral sensorineural hearing loss and long QTc, usually >500 msec. Prolongation of the QTc interval is associated with tachyarrhythmias, including ventricular tachycardia, episodes of torsade de pointes ventricular tachycardia, and ventricular fibrillation, which may culminate in syncope or sudden death.

Medical definition of torsades de pointes: ventricular tachycardia that is characterized by fluctuation of the QRS complexes around the electrocardiographic 

Torsades de pointes（フランス語で「ポイントのねじれ」）は、生命を脅かす心臓のリズム障害のいくつかのタイプの1つです。 トルサードドポアント（TdP）の場合、心室と呼ばれる心臓の2つの下部チャンバーは、心房と呼ばれる上部チャンバーよりも速く拍動し、同期していません。 increases the risk of precipitation of drug-induced torsade de pointes, which is true for both the antiarrhythmic and the non-antiarrhythmic drugs [12,13]. More than 90% of inci-dences of drug-induced torsade de pointes occur with QTc values of more than 500 ms. Women are two to three times more prone to develop drug-induced torsade de pointes Torsades de pointes (do francês "torções das pontas") são um fenômeno identificado no eletrocardiograma como um tipo de arritmia ventricular polimórfica rara, adquirida ou congênita, associada a uma perturbação na repolarização ventricular (repolarização retardada ou alongada: QT longo). É uma emergência médica e pode causar morte súbita cardíaca. [1] Hur ska jag säga Torsade de pointes i Engelska? Uttal av Torsade de pointes med 1 audio uttal, och mer för Torsade de pointes. In de praktijk zien we dat Torsades de pointes vaak pas bij de QTc boven de 500ms optreedt.

1 Definition. Die Torsade-de-Pointes-Tachykardie zählt zu den ventrikulären Tachykardien.Im EKG sieht man sich um die isoelektrische Linie drehende Wellen (Kammerkomplexe) mit Frequenzen >150 min-1, die sich etwa alle fünf bis zehn Schläge in ihrer Amplitude ändern, was zu ihrem typischen spindelförmigen Aussehen führt.
