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...
Results Baseline Characteristics A total of 19 955 ECGs from 6881 adult patients (3055 women [44.4%], 3826 men [55.6%]) were identified from January 2010 through April 2020. Median (IQR) age at first ECG was 60 (47-68) years (range, 18-100 years). The median (IQR) number of ECG...
The average maximal QTc interval was 495 +/- 21 ms and the average QTc range 95 +/- 20 ms. The maximal QTc interval was > or = 500 ms in 6 subjects and > or = 490 ms in 13. The 95% upper confidence limit for the mean 24-h QTc interval was 452 ms (men 439 ms, women ...

The purpose of this article is to critically review the current literature on quetiapine with an emphasis on emergent themes and key findings in the use of this agent for the treatment of schizophrenia. There are also continued efforts to understand, predi...

This study sought to evaluate the range and variability of the QT and corrected QT (QTc) intervals over 24 h and to assess their pattern and relation to heart rate variability.Recent Holter monitoring data have revealed a high degree of daily variability in the QTc interval. The pattern of ...
(with some exceptions) give mean values for normal QT intervals. Thus one would expect the range of normal QT intervals to be somewhat larger than the range of all possible QTp intervals. One should probably take this into account when interpreting the QT vs QTp interval statistics and graphs...
