Web1 de mai. de 2024 · It is therefore important to define if the QT of a given individual is normal or long. Such definition is based on population-based studies of ostensibly healthy individuals [6] and on case-controlled studies comparing the rate-corrected QTc of carriers vs. non-carriers of QT-prolonging genetic mutations [7, 8]. WebThe lower case letter “c” in the term “QTc” refers to a corrected value of the QT interval. As stated by FDA’s Guidance, “[b]ecause of its inverse relationship to heart rate, the measured QT interval is routinely corrected by means of various formulae to a less heart rate dependent value known as the QTc interval” ( 116 ).
