3、ns of QT Interval and Heart Rate During Exercise in Normal Men and WomenLi Weimin,Song Yingna,Li Yue,et al(First Affiliated Hospital,Harbin Medical University,Harbin,150001)AbstractThe QT interval relation to heart rate and RR interval during exercise was examined by linear regression in 52...
The normal QT interval is controversial, and multiple normal durations have been reported. In general, the normal QT interval is below 400 to 440 milliseconds (ms), or 0.4 to 0.44 seconds. Women have a longer QT interval than men. Lower heart rates also result in a longer QT interval. A...
Sudden cardiac death increases during winter months in both men and women. The heart rate–corrected QT (QTc) interval exhibits circadian variation. However, little is known about QTc interval variation with month of year. We sought to determine whether the QTc interval varies with month of year...

We attempted to evaluate whether subjects who exhibit prolonged corrected QT (QTc) interval (≥440 ms in men and ≥460 ms in women) on ECG, with and without ECG-diagnosed left ventricular hypertrophy (ECG-LVH; Cornell product, ≥244 mV×ms), are at increased risk of stroke. Among the 10...
Prolonged QTc is generally defined as >450 ms for adult males and >470 ms for adult females: 430 to 450 ms considered borderline in men 450 to 470 ms considered borderline in women (1) 440 to 460 ms considered borderline in children aged 1 to 15 years ...
