"QTcF - Fridericia's Correction Formula"^^ . "A formula which takes into account the physiologic shortening of the QT interval which occurs as the heart rate increases, permitting comparison of the QT interval across a range of rates. It is mathematically defined as: QTcF = QT/CubeRootRR(seconds) and theoretically corrects the QT interval to that which would be observed at a heart rate of 1 cycle per second.NCI" . "C1882513"^^ .
