Torsades de pointes is a polymorphic VT occurring in the setting of QT interval prolongation (acquired or congenital LQTS) and is characterized by a progressive

[1, 2] 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. This arrhythmia may cease spontaneously or degenerate into ventricular fibrillation. Torsades de pointes is caused by a prolonged QT. Almost all of the antiarrhythmics that we normally use to treat ventricular tachycardia, such as amiodarone and procainamide, will prolong the QT further, and therefore can make your patient worse. Torsades De Pointes. Torsades de pointes is a polymorphic VT occurring in the setting of QT interval prolongation (acquired or congenital LQTS) and is characterized by a progressive change of the electrical axis, typically rotating 180 degrees in approximately 10 to 12 cycles. During Torsades de Pointes the ventricles depolarize in a circular fashion resulting in QRS complexes with a continuously turning heart axis around the baseline (hence the name Torsade de Pointes).

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.

May 19, 2020 Torsades de pointes ("twisting of the points") is a form of polymorphic ventricular tachycardia characterized by a revolving QRS axis producing

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)?

Psykofarmaka-inducerad QTc-tid högre än 500 ms eller ökning med > 60 ms innebär signifikant ökad risk för arytmier och Torsade de pointes. Kan potentiellt

Patients experiencing Torsades de pointes may experience palpitations, hypotension, syncope, apprehension, pallor, sweating, nausea, and respiratory arrest. 2021-04-09 · Torsade de pointes är en sällsynt komplikation till tablettintoxikation, men QTc-förlängning är vanligt och Giftinformationscentralen får ofta frågor om handläggningen. Behandlingen av läkemedelsutlöst torsade de pointes är väldokumenterad, däremot har det saknats indikationer för arytmiövervakning och för åtgärder som förhindrar torsade de pointes vid intoxikationer med Risk of torsades de pointes The risk of developing torsades de pointes in association with QT-pro-longing drugs depends on a num-ber of factors.

2021-04-03 Torsades de pointes may be self-limited or may progress to VENTRICULAR FIBRILLATION. A malignant form of polymorphic ventricular tachycardia that is characterized by HEART RATE between 200 and 250 beats per minute, and QRS complexes with changing amplitude and twisting of the points. Medical definition of torsades de pointes: ventricular tachycardia that is characterized by fluctuation of the QRS complexes around the electrocardiographic baseline, is typically caused by a long QT interval, and may lead to life-threatening ventricular fibrillation. Torsades de-pointes 1. PHARMACOTHERAPYOF TORSADEPOINTES 2. Torsade de pointes or torsades is a Frenchterm that literally means "twisting of thepoints" is a ventricular tachycardia associatedwith a long QT time on the resting ECG. During Torsade de pointes the ventriclesdepolarize in a circular fashion resulting inQRS complexes with a continuously turningheart axis around the baseline (hence 2018-07-02 The term torsade de pointes has also been used to describe polymorphic ventricular arrhythmias in which QT intervals are not prolonged.
