A machine learning model was more effective at detecting congenital long QT syndrome on resting ECGs than manual measurement of QT intervals by arrhythmia experts, in a new study. Researchers ...

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 ...

Five factors underlie the ongoing overdiagnosis and misdiagnosis of long QT syndrome (LQTS), including temporary QT prolongation following vasovagal syncope, a "pseudo"-positive genetic test result, ...

Timothy syndrome (TS), a rare autosomal-dominant disorder, is characterized by presence of a heart arrhythmia (long QT syndrome), which causes the cardiac muscle to take longer than usual to recharge ...

People diagnosed with one of the most common inherited heart arrhythmias, called Long QT syndrome (LQTS), can safely engage in vigorous exercise without any added risk for sudden death or cardiac ...

Women with congenital long QT syndrome (LQTS) need to be cautious when taking an oral contraceptive (OC), observational data suggest—those on progestin-only pills are nearly three times more likely to ...

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 ...

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 ...

SAN FRANCISCO -- Cardiac repolarization dynamics seemed to cycle in sync with the menstrual cycle of some people with congenital and drug-induced long QT syndrome (LQTS), a small prospective study ...
