Note also that some texts report theupper limitsof normal for the QTc as 0.45 sec (450 msec) for women. A number of factors can abnormally prolong the QT interval (Fig. 2-13). For example, this interval can be prolonged by certain drugs used to treatcardiac arrhythmias(e.g.,amiodarone...

You can use this QTc calculator to determine the corrected QT interval (QTc) in seconds in accordance with someone's heart rate (beats per minute). The QTc calculator relies on the formulas that are most commonly used to determine a QTc interval
What is a normal QTc interval? In general, the normal QT interval is below 400 to 440 milliseconds (ms), or0.4 to 0.44 seconds. Women have a longer QT interval than men. Lower heart rates also result in a longer QT interval.
The means of CRP level in women, though over normal range, increased significantly as QTc interval was longer, independent of confounding factors, while those of men were on the borderline of significance. However, compared to normal range of QTc interval, prolonged QTc interval was associated ...
Several formulae, the Bazett, Fridericia, Framingham and Hodges formulae, correct QT (QTc) for heart rate variability and an interval of 4450 ms for men and 460 ms for women is generally accepted as upper limit of normal (Bazett, 1920; Fridericia, 1920; Hodges et al, 1983; Sagie et al...
460 ms for women is generally accepted as upper limit of normal (Bazett, 1920;Fridericia, 1920;Hodges et al, 1983;Sagie et al, 1992;Al-Khatib et al, 2003). Ventricular arrhythmias, particularly torsades de pointes (TdP), correlate with a QTc interval of >500 ms (Bednar et al, ...
There were 722 (63.33 %) men with a mean age of 43.71 ± 15.21 years and 418 (36.67 %) women with a mean age of 45.12 ± 15.72 years. In the overall sample, the mean HR was 78.92 ± 12.25 bpm and the uncorrected QT interval was 388.49 ± 42.74 ms. There was no gender ...
