Calculate qtcf by fridericia's formula
WebNov 1, 2013 · The calculation of the corrected QT interval (QTc) is particularly problematic in patients during atrial fibrillation (AF). The aims of this study were to compare the QTc calculated using Bazett's formula in AF and sinus rhythm (SR) and determine whether alternative methods for QT correction were superior to Bazett's, in an effort to define the … WebQTcV - Van de Water's Correction Formula. A mathematic formula defined as: QTcV = QT-0.087 [ (60/Heart Rate)-1] (seconds). It permits comparison of the QT interval across a range of rates, while accounting for the progressive shortening of the QT interval which occurs as the heart rate increases. (NCI Thesaurus)
