Objectives The short QT syndrome is a cardiac channelopathy characterised by accelerated repolarisation which manifests as a short QT interval on the ECG. The definition of a short QT interval is ...

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

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 ...

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 ...

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 ...

SAN FRANCISCO, CA—Consuming a large quantity of grapefruit juice has effects on the QT interval in healthy adults similar to those seen with moxifloxacin, an antibiotic with known QT-prolonging ...

Aim To determine factors affecting the QT interval in athletes and find an improved means of QT correction (QTc) Method Data was gathered from the CAYA (Cardiovascular Assessment in Young Athletes) ...

"The net increase in QT interval caused by grapefruit among healthy volunteers was small, but in the range that, if grapefruit juice were a new drug in development, the results of the present study ...

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 ...

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 ...

Diagnosis of LQTS may be prompted by symptoms or may be made as a chance finding on Electrocardiography (EKG or ECG). Diagnosis of LQTS includes looking at a patient’s medical history, physical ...
