In long QT syndrome, the heart muscle takes longer than normal to electrically recharge after it contracts. A test called an electrocardiogram (also called an ECG or EKG) can detect this problem.

Whether or not your children will develop long QT syndrome depends on the type of the disease. Most of the time, all the children have to get an EKG and sometimes another test to see if further ...

For over 100 years, QTc assessment and monitoring has relied heavily on the 12-lead electrocardiogram (EKG). But that could be about to change, according to this research.

The object was to compare the QTc values from a 12-lead EKG to those from the prototype hand-held EKG device used with a smartphone. Both sets of EKGs were given at the same clinical visit, ...

Usually the purview of bulky 12-lead ECG systems, QT-intervals could potentially be assessed anywhere a modified smartphone can go, suggesting a possible screening 'paradigm shift,' researchers say.

For over 100 years, QTc assessment and monitoring has relied heavily on the 12-lead electrocardiogram (EKG). But that could be about to change, according to this research.

BOSTON — Artificial intelligence using deep neural networks identified patients with congenital long QT syndrome whose ECG reading was normal, according to findings presented at the Heart Rhythm ...

Patients with a prolonged QTc can experience rapid heartbeats, and in some cases, sudden cardiac death. Researchers assessed AliveCor’s KardiaMobile 6L EKG device by comparing it to a 12-lead ...

European Journal of Human Genetics - Genetics of the ECG: QT or not QT- A genetic analysis of a complex electrophysiological trait confirms several previously detected associations ...

A simple electrocardiogram (ECG) ... QT prolongation was associated with a 1.85-fold increased risk of dying within a year after adjusting for age, co-existing conditions and severity of COVID-19.

The QT interval is a measurement on the ECG that represents how long it takes for the heart to recover after it contracts before it's ready to contract again.
