Background: Polymorphic ventricular tachycardia (VT) without QT prolongation is well
described in patients without structural heart disease (mainly idiopathic ventricular fibrillation …

Aims We recently reported that patients with coronary artery disease (CAD) who develop
polymorphic ventricular tachycardia (VT) during the healing phase of an acute coronary …

Aims Distinctive types of polymorphic ventricular tachycardia (VT) respond differently to
different forms of therapy. We therefore performed the present study to define the …

Ventricular arrhythmia (VA) in structurally normal hearts can be broadly considered under
non–life-threatening monomorphic and life-threatening polymorphic rhythms. Monomorphic …

Objectives This study aimed to review the utility of quinidine in patients presenting with
recurrent sustained ventricular arrhythmia (VA) and limited antiarrhythmic drug (AAD) …

This article reviews the current understanding of the mechanisms for polymorphic VT, its
clinical manifestation, and therapies. The various idiopathic long QT syndromes and …

A67-year-old woman with advanced heart failure ac-companying idiopathic dilated
cardiomyopathy had a broad QRS complex on the ECG and significant inter-and …

To determine the prevalence and importance of proarrhythmic events secondary to the
initiation of quinidine therapy in outpatients with benign or potentially lethal ventricular …

In up to 10% of patients who present with ventricular tachycardia (VT), obvious structural
heart disease is not identified. In such patients, causes of ventricular arrhythmia include right …

The polymorphic ventricular tachycardia (PVT) is uncommon arrhythmia with multiple
