In de praktijk zien we dat Torsades de pointes vaak pas bij de QTc boven de 500ms optreedt. 2 Alternatief kan er gebruik worden gemaakt van het QT Nomogram om te zien of er op basis van QT-tijd en hartfrequentie sprake is van verlengde QT-tijd (zie kader). 3 Met name bij een lage hartfrequentie is deze accurater (ondercorrectie bij Bazet).

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.

Introduction: Torsades de Point (TdP) is a rare but potentially lethal cardiovascular consequence of trazodone overdose. Description: A 76 year-old woman with Torsades de pointes ("twisting of the points") is a type of polymorphic ventricular tachycardia that presents with shifting sinusoidal waveforms on the Medical definition of torsades de pointes: ventricular tachycardia that is characterized by fluctuation of the QRS complexes around the electrocardiographic Torsade de pointes in a long QT syndrome type 2 patient.

However, the outlook for people managing the condition with the appropriate treatment is excellent. Torsades de Pointes Torsades is defined as the combination of polymorphic ventricular tachycardia plus a prolonged QT-interval. Torsades can be caused by either congenital long-QT syndrome or acquired long-QT syndrome (due to electrolyte abnormalities and/or medications). The vast majority of torsades results from acquired long-QT syndrome Torsade de pointes is an uncommon and distinctive form of polymorphic ventricular tachycardia (VT) characterized by a gradual change in the amplitude and twisting of the QRS complexes around the isoelectric line (see the image below). Torsade de pointes, often referred to as torsade, is associated with a prolonged QT interval, which may be co Torsades de pointes is a distinctive polymorphic ventricular tachycardia in which the QRS amplitude varies and the QRS complexes appear to twist around the baseline. Torsades de pointes is associated with a prolonged QT interval, which may be congenital or acquired.
