Long QT syndrome (LQTS) is a cardiac disorder characterized by prolonged repolarization
of the heart's electrical cycle, which can be observed as an extended QT interval on an …

Background: Although well-defined clinically and electrocardiographically, Acquired Long
QT Syndrome (LQTS) remains elusive from a pathophysiologic point of view. An increasingly …

Since its initial description by Jervell and Lange-Nielsen in 1957, the congenital long QT
syndrome (LQTS) has been the most investigated cardiac ion channelopathy. Although …

The long QT syndrome has become the focus of considerable scientific attention in recent
years because of the discovery of several genes responsible for its development. These …

Congenital long QT syndrome (LQTS) is a familial disorder characterized by ventricular
repolarization that makes carriers vulnerable to malignant ventricular tachycardia and …

transmission, characterized primarily by prolongation of the QT interval and by the …

With an incidence as high as 1 in 2,000–2,500 live births, long QT syndrome (LQTS) is often
characterized clinically by prolongation of the heart rate corrected QT interval (QTc) on a 12 …

Congenital long QT syndrome is an inherited disorder of cardiac repolarization that

BACKGROUND: Many classes of medications initiated by clinicians can cause adverse
events, such as cardiac disturbances. One such adverse outcome is that of acquired long QT …

Since it was first reported 50 years ago, the long QT syndrome (LQTS) is now recognized as
