There are significant knowledge deficits among health care practitioners, including cardiology specialists, regarding the measurement of the QT interval and identification of QT-prolonging medications.
LaPointe et al. (2003) reported a cross-sectional. Survey of QT interval knowledge was evaluated on Accurate measurement of a sample QT interval and identification of QT-prolonging medications. A survey of 334 health care practitioners revealed significant knowledge deficits, with only 42% able to accurately measure a sample QT interval and 63% able to identify QT-prolonging medications.
