Adrenal and extra-adrenal pheochromocytomas presenting as life-threatening ventricular arrhythmias: Report of three cases

Indian Heart Journal, 2016
Pheochromocytoma patients can rarely have prolonged QT interval in the ECG. We report three cases of pheochromocytoma in females presenting with ventricular arrhythmia; two had torsades de pointes and a third patient had frequent VPCs and nonsustained ...

Beat‐to‐beat variability of ventricular repolarization reveals sex‐specific instability and proarrhythmic risk

The Journal of Physiology, EarlyView.
Abstract figure legend A mechanistic framework linking sex‐dependent dynamical instability to proarrhythmic risk. Sex‐specific human ventricular models show that upstream modulators, including biological sex, hormones, drugs and heart disease, promote steeper APD restitution in female than male and enhance dynamical instability.

Sleep-Associated Torsades de Pointes: A Case Report

Clinical Practice and Cases in Emergency Medicine, 2017
Torsades de Pointes (TdP) is a polymorphic ventricular tachycardia that occurs in the presence of an acquired or congenital long QT syndrome (LQTS). We present the case of a 57 year-old man with end-stage renal disease on methadone maintenance in which ...

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

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 ...

hERG1 channels and potential therapeutics for long QT syndrome

The Journal of Physiology, EarlyView.
Abstract figure legend Prolonged QT results from hERG1 channel dysfunction. (A) Physiological anterograde trafficking of hERG1 channels to the plasma membrane, leading to a normal electrocardiogram. (B) Prolonged QT results from the presence of fewer hERG1 channels on the plasma membrane due to decreased anterograde trafficking or reduced function due ...

Antipsychotic Drug Interactions and Short‐Term Mortality Risk in People With Dementia: A National Cohort Study

Clinical Pharmacology &Therapeutics, Volume 120, Issue 4, Page 1081-1091, October 2026.
Antipsychotics are often prescribed in the management of behaviors and psychological symptoms of dementia. While the potential harms of antipsychotic use in people with dementia have been established, little is known about the risk associated with antipsychotic drug–drug interactions (DDIs). This study aims to examine the patterns of antipsychotic DDIs

Suppression of torsades de pointes by atropine [PDF]

, 1998
A 67 year old woman with a history of chronic atrial fibrillation presented with asthma cardiale. She took no medication and there was no family history of long QT syndrome. She was treated with furosemide, nitroprusside, acenocoumarol, and digoxin.

Torsades de Pointes associated with QT prolongation after catheter ablation of paroxysmal atrial fibrillation

Indian Pacing and Electrophysiology Journal, 2017
A 79-year-old woman who underwent catheter ablation for paroxysmal atrial fibrillation presented with Torsades de Pointes (TdP). Aggravation of prolonged QT interval which is most likely due to neural modulation by catheter ablation, played major role in

Effectiveness of Bachmann's Bundle Pacing in a Patient With Severe Heart Failure and Refractory Atrial Fibrillation

Journal of Arrhythmia, Volume 42, Issue 5, October 2026.
This case report highlights CRT‐D with Bachmann's bundle pacing (BBP) in a patient with severe heart failure and refractory atrial fibrillation. BBP preserved atrioventricular conduction without PR prolongation, maintained left ventricular–only pacing, and was associated with suppression of atrial fibrillation and improvement in left atrial contractile
