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 QT interval is the time from the beginning of the QRS complex, representing ventricular depolarization, to the end of the T wave, resulting from ventricular repolarization. The normal QT interval ...
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 ...
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 ...

"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 ...
This is a preview. Log in through your library . Abstract Purpose To examine the relationship of metabolic syndrome with corrected QT interval duration. Methods In a cross-sectional analysis of NHANES ...
LQTS can be inherited or acquired through medications or electrolyte imbalances, with family history being a significant risk factor. While some individuals with LQTS may not experience symptoms, ...
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 ...
Grapefruit juice is already listed as a substance to avoid when taking QT-prolonging medications because it increases the toxicity of many drugs. Investigators have now confirmed the QT-prolonging ...
