Objective: To assess health care practitioners' ability to correctly measure the QT interval, and to identify factors and medications that may increase the risk of QT-interval prolongation and ...

Boston, MA - Patients who receive high doses of the antidepressants citalopram or escitalopram could potentially develop QT-interval prolongation, a marker of a slight increased risk for ventricular ...

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 ...

Uncertainty remains regarding the value of heart-rate-corrected QT interval (QTc) prolongation on electrocardiogram for predicting cardiovascular disease (CVD), particularly among Asian populations.

Department of Molecular Pharmacology & Experimental Therapeutics, Mayo Clinic, Rochester, Minnesota, USA Correspondence to Dr M J Ackerman, Long QT Syndrome Clinic and the Mayo Clinic Windland Smith ...

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 is a leading cause of sudden death in young persons, with a prevalence exceeding 1 in 2000. It is characterized by prolongation of the QT interval, aberrant T-wave morphologic ...

Similarly, subjects with an increased QT dispersion (QTd), which may mirror discrepant repolarization characteristics of different areas of the heart, show an increased cardiovascular mortality and ...

The QT interval on an ECG is a vital marker of heart health, but measuring and interpreting it correctly can be tricky. Advances in formulas, regulatory guidance, and AI-powered tools are helping ...

The QT interval on an electrocardiogram signifies the time required for the heart to repolarize after depolarization. It has long been appreciated that a long QT interval predisposes patients to ...

This Journal feature begins with a case vignette highlighting a common clinical problem. Evidence supporting various strategies is then presented, followed by a review of formal guidelines, when they ...

Long QT interval is a condition that affects the heart’s electrical rhythm, which can lead to potentially life threatening arrhythmia. Behind the pumping action of the heart is an electrical ...
