WebThe QT values can be obtained from the ECG test. This QTc calculator is designed to show the QT corrected interval for heart rate extremes because it returns the estimations by 4 different equations as presented below: QT corrected interval: by Bazett’s formula: QTc = QT/√(RR in seconds) by Fridericia’s formula: QTc = QT/(RR^0.33)
