Numerous attempts at correction have been made, but Bazett's correction (QT/square root of RR) remains the current standard. In stable sinus rhythm, a QT interval corrected for heart rate (QTc) of > 0.44 sec is considered abnormal. In this study, in the presence of sinus arrhythmia, the...
A, Normal sinus rhythm; the Bazett formula is used to correct the QT interval for the heart rate. B, Atrial fibrillation; QT interval is calculated by taking the average of QT intervals with shortest and longest preceding R-R intervals. Pharmacokinetic Interactions With Selected QT-Prolonging ...

Patients with mild renal/hepatic/cardiac dysfunction may also be excluded because of arbitrary “cutoffs” rather than clinical relevance (usually >60 mL/min for GFR, >50% ejection fraction or <450 milliseconds for corrected QT interval for cardiac status, <2–3 times upper limit of normal (...

Background: Prolonged QTc (corrected QT) interval and torsades de pointes (TDP) are associated with hypocalcemia, hypomagnesemia, hypokalemia, possibly alkalosis and may result in syncope and sudden cardiac death. Do you do CPR for torsades? If torsades de pointes is present, then give magnesium ...
QT intervals: QTmax (maximal QT interval duration in the 12 ECG leads), QTc (heart rate corrected QTmax), QTm (mean QT interval duration in all measurable leads), QTd (QT interval dispersion), QTII (QT interval duration in lead DII), QTIIc (heart rate corrected QTII), and T wave ...
