Congenital long QT syndrome (LQTS) is caused by mutations in genes encoding cardiac ion channels, and is characterized by prolongation of the ventricular cardiac action potential, which lengthens the ...

Long QT syndrome (LQTS) is potentially lethal if left untreated. Accurate diagnosis is, therefore, vital. Patients with LQTS have impaired adaptation of the QT interval in response to changes in heart ...

Prolonged QT syndrome (a.k.a. Long QT Syndrome) consists of multiple different variations including long QT type 1-12, Romano-Ward syndrome and Jervell-Lange-Nielsen syndrome. A prolonged QT interval ...

An innovative analysis of shared segments within the genome - an indication of distant "relatedness" - has identified undiagnosed cases of Long QT syndrome, a rare disorder that can lead to abnormal ...

Long QT syndrome (LQTS) is the prototypic cardiac channelopathy underscored by profound genetic and phenotypic heterogeneity. In 1991, the first LQTS chromosome locus was identified and subsequently ...

Less than 1 percent of the population has been diagnosed with Long QT syndrome – a rare heart condition that can cause chaotic, sometimes fatal, heart rhythms. Now, Virginia Tech researchers at the ...

Research confirms that grapefruit juice prolongs the QT interval. This finding has implications for patients taking medications that prolong the QT interval and may have implications for patients with ...

ROCHESTER, MN — A significant number of patients given implantable cardioverter defibrillators (ICDs) for long-QT syndrome (LQTS) receive them for reasons outside of current guidelines, and many ...

As more consumer-facing devices add features to measure the heart’s electrical activity, companies are looking for new ways to turn this data into valuable health information. AliveCor, a startup that ...

The QT interval is the time from the beginning of the QRS complex (ventricular depolarization) to the end of the T wave (ventricular repolarization). The normal QT interval is controversial and ...
