Diagnosing Torsades De Pointes Based on Correlation to QT Interval: A Systematic Review. [PDF]

Cureus, 2022
Torsades de Pointes (TdP) is a rare form of tachyarrhythmia which can potentially be fatal due to its tendency to degenerate into ventricular fibrillation.

Class III Antiarrhythmics and Periprocedural Torsades de Pointes [PDF]

JACC: Case Reports, 2023
This case series describes 2 women on prolonged therapy with class III antiarrhythmics who developed torsades de pointes polymorphic ventricular tachycardia in the setting of catheter ablation for atrial fibrillation as a result of QTc prolonging factors.

Clomipramine potentially induced fatal torsades de pointes in a patient with acute decompensated heart failure: a case report [PDF]

Frontiers in Psychiatry
BackgroundWhile clomipramine is generally considered lower risk for QT prolongation among tricyclic antidepressants, its potential to induce torsades de pointes (TdP) remains poorly characterized, particularly in patients with multiple risk factors.Case ...

Ticagrelor-Induced Torsades de Pointes following Myocardial Infarction [PDF]

Case Reports in Cardiology, 2022
We report a case of excessive QT prolongation and subsequent torsades de pointes (TdP) following the administration of ticagrelor in a 58-year-old male patient. The patient had no suspected cause of QT prolongation.

Bigeminy with Prolonged QT Interval as an Ominous Sign for Impending Torsades de Pointes: A Case Report [PDF]

Clinical Practice and Cases in Emergency Medicine
Introduction: Ventricular ectopic beats and corrected QT interval (QTc) prolongation are both relatively common entities that are typically benign. It is difficult to predict subsequent dysrhythmias from either electrocardiogram (ECG) feature.

Genome wide analysis of drug-induced torsades de pointes: lack of common variants with large effect sizes.

PLoS ONE, 2013
Marked prolongation of the QT interval on the electrocardiogram associated with the polymorphic ventricular tachycardia Torsades de Pointes is a serious adverse event during treatment with antiarrhythmic drugs and other culprit medications, and is a ...

Mechanisms of torsades de pointes: an update [PDF]

Frontiers in Cardiovascular Medicine
Torsades de Pointes (TdP) refers to a polymorphic ventricular tachycardia (VT) with undulating QRS axis that occurs in long QT syndrome (LQTS), although the term has been used to describe polymorphic ventricular tachyarrhythmias in which QT intervals are

A rare case of myotonic dystrophy type 1 presenting with Torsades de pointes

IHJ Cardiovascular Case Reports, 2023
Myotonic Dystrophy (DM) is the most common form of muscular dystrophy with onset in adults. Cardiac manifestations are common in DM, but ventricular arrhythmias are uncommon and torsades de pointes is rarely described.
