Torsades de pointes (akronim TdP) je specifičan oblik polimorfne ventrikulаrne tahikardije kod bolesnika sa dugim QT–intervalom.Karakteriše se na EKG brzim, nepravilnim QRS–kompleksima, koji kao da se prelamaju (uvijaju) oko izoelektrične linije. 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.

It differs from other forms of ventricular tachycardia by its morphological features, underlying mechanism, and modes of therapy. Recognizing torsade de pointes is of major clinical importance, as standard antiarrhythmic r … What causes Torsades de Pointes (TdP)? The cause of torsades is a long QT interval (an abnormally long repolarization of the heart) that turns into a continuous circular electrical route in the ventricles.

Torsades can be caused by either congenital long-QT syndrome or acquired long-QT syndrome (due to electrolyte abnormalities and/or medications).

Les médecins parlent de torsade de pointe car le tracé sur l'électrocardiogramme semble montrer que l'axe du coeur "tourne sur lui-même". 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.

It is characterized by rapid, irregular QRS complexes, which appear to be twisting around the electrocardiogram (ECG) baseline. This arrhythmia may cease spontaneously or degenerate into ventricular fibrillation. 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.
