  • Title: Heart rate dependent modification of the QTc cut-off values can improve accurate evaluation of QT prolongation.
    Author: Sadanaga T, Sadanaga F, Yao H, Fujishima M.
    Journal: Am J Cardiol; 2004 Mar 15; 93(6):772-5. PubMed ID: 15019891.
    Abstract:
    Significant amounts of over- and underestimation to detect QT prolongation were observed using Bazett's formula or Fridericia's formula for heart rate correction with any fixed QTc cut-off value. Heart rate dependent modification of the QTc cut-off values can improve accurate evaluation of QT prolongation.
