The QT interval corrected for heart rate (QTc) was calculated using the Bazett formula.
Since the QT interval duration various with the heart rate the corrected QT interval (QTc), which standardises the QT interval for rate from the EKG, was calculated using the Bazett formula.
It is essential to confirm the QT interval by using the Bazett formula (QTc equals the QT in seconds divided by the square root of the RR interval in seconds) for all patients with a history that suggests a possible arrhythmia.
Vrtovec et al recorded 12 lead ECG and calculated QTc manually with the help of calipers and by using Bazett formula.
The intervals of QT were corrected according to heart rate (HR) using the Bazett formula "Corrected QT interval (QTc) = QT/[square root of R - R]" and expressed as QTc.
The main limitations are due to additional sources of variability of the QT interval, the use of the Bazett formula, methodological difficulties in delineating the end of the T wave, lack of standardization for Tpe and QTd and no direct arrhythmia data.
The QTc interval was calculated using the Bazett formula; QTc (ms) = QT measured/[square root of (RR)] (where RR is the RR interval).
Nine hours following intravenous amiodarone administration, her QTc interval was 613 ms, using the Bazett formula.
For example, Burnside had endorsed Lord's bill of exchange as payable to Bruce, de Ponthieu, Bazett & Co.
To adjust for heart rate, correction formulae, such as Fridericia and Bazett, are used to generate a corrected QT, or QTc.
