QTc (Bazett, Ped(z)-style) is a electrocardiography tool commonly applied in Cardiology. Corrected QT (ms) from measured QT and heart rate or RR interval using Bazett: QTc = QT / √RR (RR in seconds; RR = 60/HR). Same role as Ped(z) QTc; for other corrections use the existing Corrected QTc tool. Not affiliated with pedz.de. Use the interactive calculator for inputs, limitations, and primary references.
