The duration of the QT interval as measured by 12-lead electrocardiography is a measure of myocardial repolarization and is widely used to describe cardiac abnormalities, to determine the presence of ...
What is the best way to estimate the QT interval on the ECG? What is the equation for QTc? A good way to estimate if the QT interval prolonged is by checking its relation to the R-R interval. If the ...
One of the principal tasks of an oncologist is to determine whether to administer, reduce the dose, or hold chemotherapy on the basis of patient characteristics, organ function, and toxicities. These ...
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 ...

Tyrosine kinase inhibitors (TKIs) are associated with prolongation of the QTc interval on the electrocardiogram (ECG). The QTc-interval prolongation increases the risk of life-threatening arrhythmias.
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 ...
