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 ...

The maternal heart significantly adapts to the circulatory needs of pregnancy, but the effect of pregnancy on ventricular repolarization is poorly understood. The aim of this study was to quantify ...

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 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 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 ...

Having access to less intrusive QT interval measurement with flexibility around the time and place of the appointment is important 3.1 Psychiatric service user experts explained that it is important ...

Drinking large quantities of grapefruit juice may prolong the QT interval, especially in women and those who already have long QT syndrome (LQTS), new research suggests. Investigators at Tel Aviv ...

Congenital long-QT syndrome is a disorder resulting in ventricular arrhythmias and sudden death. The most common forms of the long-QT syndrome, types 1 and 2, are caused by mutations in the ...

Research confirms that grapefruit juice prolongs the QT interval; this finding has implications for patients taking medications that prolong the QT interval and may have implications for patients with ...
