A comparison of commonly used QT correction formulae: the effect of heart rate on the QTc of normal ECGs. J Electrocardiol. 2004; 37 Suppl:81-90. 2. Sagie A, Larson MG, Goldberg RJ, Bengtson JR, Levy D. An improved method for adjusting the QT interval for heart rate (the Framingham...
The normal QTc in men is less than 450 ms and less than 470 ms in women [11]. For the purpose of the study and to include true positive cases, QTc was considered prolonged if more than 460 ms in men and more than 480 ms in women on any EKG done during hospital stay. This cut ...

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 ...
However, compared to normal range of QTc interval, prolonged QTc interval was associated with elevated CRP level, defined as more than 95 percentile of CRP, in men and women, respectively. Conclusions: Prolonged QTc interval in middle-aged men and women is associated with the elevated CRP, ...

Background: Cardiac syndrome X is usually diagnosed in the presence of typical exertional chest pain, a positive response to exercise testing, and normal coronary angiograms. The underlying pathogenic mechanisms are speculative, but myocardial ischemia and increased sympathetic activity have been implicate...

Results: QTc interval was significantly longer in patients than in normal controls. The prevalence of QTP is 8.26% in Chinese hospitalized patients with chronic schizophrenia. More women than men displayed QTP. Compared with patients without QTP, the patients with QTP had significantly higher concrete...
Calculated QTc values using Bazett formula resulted in 9958 ECGs (49.9%) classified as normal, 6263 (31.4%) classified as grade 1, 1948 (9.8%) classified as grade 2, and 1786 (9.0%) classified as grade 3 (Figure 1C). A total of 340 ECGs (1.8%) were classified as grade 3 toxicity...
