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.

Hypocalcemic torsades de pointes
Journal of Electrocardiology, 1989 Torsades de pointes is a unique form of ventricular tachycardia that occurs in the presence of prolonged QT interval. Many predisposing factors have been identified. A classical form of torsades de pointes occurring in the presence of hypocalcemia and prolonged QT interval in an elderly woman is reported.

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

Bigeminy with Prolonged QT Interval as an Ominous Sign for Impending Torsades de Pointes: A Case Report [PDF]
Clinical Practice and Cases in Emergency MedicineIntroduction: 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.

Mechanisms of torsades de pointes: an update [PDF]
Frontiers in Cardiovascular MedicineTorsades 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.

Emergency Medicine Journal, 2002 A case is described of torsade de pointes in a 41 year old woman with pre-existing QTc prolongation, potentially exacerbated by treatment with sotalol. Previous cardiac investigations had been normal and after a second episode of ventricular fibrillation the patient was referred for electrophysiological studies.

Risk of Cardiac Lesion with Chronic and Acute Use of Loperamide—An Integrative Review
Journal of Cardiovascular Development and Disease, 2022 Loperamide is a synthetic opioid commonly used as an antidiarrheal due to its activation of u-opioid receptors in the myenteric plexus. In therapeutic doses, it inhibits peristalsis and has anti-secretory and anti-motility effects, until metabolized by ...
