WebFeb 23, 2024 · Since the 1920s, the Bazett formula (QTc=QT/RR1/2) has been primarily used to derive the “heart rate-corrected QT interval,” or QTc, in clinical and research settings. Most computerized ECG interpretation … WebThe global group QTc-heart rate (HR) correlation coefficients were calculated as Bazett 0.33, Fridericia 0.24, Framingham 0.26, and Hodges 0.11, with the uncorrected QT-HR correlation being 0.82. Overall by far, Hodges QTc is significantly less correlated with HR compared to the others.
