WebThe corrected QT (QTc) interval is used to standardise the values. The most commonly used formula used to calculate QTc is Bazett's formula: Q T c = Q T / R R (1) where QTc is the corrected QT interval, QT is the absolute QT interval, and √ RR is the preceding RR interval. Webby Fridericia’s formula: QTc = QT/ (RR^0.33) by Framingham’s formula: QTc = QT + 0.154 (1-RR) by Hodges’s formula: QTc = QT + 1.75 (HR - 60) Where: RR interval = 60 / HR HR = Heart rate in beats per minute. Moreover it returns the QT corrected interval expressed in both seconds and milliseconds. peavy portable sound system 299 or less https://cascaderimbengals.com
