WebIf you plug in a few variables into a QTc formula, you will get a number result. You then compare this number with the two normal values (male 0.39, female 0.41). This method allows computers in 12 lead equipment to quickly calculate the QTc and print it on the EKG record. It also allows Paramedics to quickly assess the QT interval. WebMeasured QT interval Corrected QT interval is: seconds QTC calculated using Bazett's formula: QTC = QT / ÖRR
