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 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 ...
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 ...
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 ...
