THE case reported below represents a new and very distinct clinical entity. The young patient was observed by us for some years. It was hoped that a similar combination of clinical findings might be ...

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 ...

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 ...

Minneapolis, MN - An increased duration of the QTc points to an elevated risk for coronary heart disease (CHD) and cardiovascular disease (CVD) mortality in black and white healthy men and women, ...

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 ...

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 ...

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 ...

DEAR MAYO CLINIC: I recently read that long QT syndrome is quite common. What is it, and how is it diagnosed? I have read that fainting may be one sign of the disorder. Can long QT syndrome be treated ...

Researchers have been using artificial intelligence (AI) to develop a mobile device that can identify certain patients at risk of sudden cardiac death. Researchers from Mayo Clinic and AliveCor Inc.

AliveCor and Mayo Clinic have partnered to test whether artificial intelligence can identify inherited long QT syndrome in EKG results. The syndrome causes about 3,000 to 4,000 sudden deaths in ...

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 ...

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 ...
