WebThe corrected QT interval (QTc) is the measured QT interval adjusted to a heart rate of 60 beats/min and is obtained by dividing the measured QT interval by the square root of the preceding RR interval: 8-1 Thus, a measured QT interval of 0.35 seconds at a heart rate of 90 beats/min yields a QTc: WebApr 1, 2008 · Because the QT interval varies with heart rate (lengthening with bradycardia and shortening with tachycardia), the QT interval is corrected (QT C) for heart rate using Bazette's formula: QT C = QT/√RR (Fig. 2). The QT interval is normally between 0.30 and 0.44 s. Any QT C interval >0.44 s is considered prolonged.
