Congenital long QT syndrome (LQTS) with atrioventricular block is a rare and malignant
arrhythmia, which usually responds poorly to traditional β-blocker therapy. We describe a …

In the past decade, molecular genetic research has established a causal link between
mutations in genes encoding ion channels or other membrane components and a vast array …

In their paper published in this issue of Heart, Birati and colleagues report the cardiac
location from which arise the premature ventricular beats initiating torsades de pointes (TdP) …

Polymorphic ventricular tachycardia, which occurs during the subacute phase of myocardial
infarction (MI) or ischemia and is not related to ongoing ischemia, has recently been …

Case: We describe a unique instance of Wolf-Parkinson-White Pattern and Congenital Long
QT Syndrome in the same patient. A 31 year old female with past medical history of pre …

Aims The right ventricular outflow tract (RVOT) and tricuspid annulus (TA) are common
origins for idiopathic PVCs from the right ventricle. We sought to clarify the characteristics of …

Background The aim of present study is to evaluate the predictive value of QTc dispersion,
Tp-Te interval and Tp-Te/QT ratio for idiopathic monomorphic outflow tract ventricular …

Long QT syndrome (LQTS) is an inherited channelopathy that causes sudden death in all
ages owing to polymorphic ventricular tachycardia. Although it is uncommon, individuals …

Coupling Intervals and Polymorphic QRS Morphologies. Introduction: Premature ventricular
contractions (PVCs) arising from the right ventricular outflow tract (RVOT) can trigger …

Introduction Congenital long QT syndrome (LQTS) and catecholaminergic ventricular
tachycardia (CPVT) are less prevalent cardiac ion channelopathies than Brugada syndrome …
