“…The average QTc interval using Bazett's formula was 445.1 ms, with 60% of the patients showing a QTc prolongation above 440 ms, which was about 28 ms longer than that of Hodges' formula, when the HR was up to 100 beats.min )1 immediately after intubation in the saline group (data not shown). Unfortunately there is no general consensus on the best formulas, including those of Fridericia, Framingham, or Hodges, for use in clinical practice [15,[26][27][28]. Hodges' formula, which may be one of least correlated with HR [15], was used rather than Bazett's formula in our study.…”
