WebIn a regular rhythm ECG, the heart rate may be derived from counting the number of large and small squares between two QRS complexes and examining the RR interval … 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)
