Results:Heart rate (P= .073), QT interval (P= .432) and QTc interval (P= .179) were similar before and after thyroid surgery. Tp-e interval (84.6 ± 13.1 vs 77.2 ± 10.9; P= .031), Tp-e/QT ratio (0.23 ± 0.04 vs 0.21 ± 0.04; P< .001), Tp-e/QTc ratio (0.21± 0.04 ...

. The normal values for the QT interval depend on the heart rate. As the heart rate increases (RR interval shortens), the QT interval normally shortens; as the heart rate decreases (RR interval lengthens), the QT interval lengthens. TheRR interval, as described later, is the interval (time...
ECG: Corrected QT Calculate the corrected QT interval About The most commonly used QT correction is that of Bazett which was proposed in 1920. Unfortunately the Bazett correction overcorrects with heart rates >110 bpm and undercorrects with heart rates < 60 bpm. The Hodges correction and the Fr...

Since increases in heart rate result in shortening of the QT interval, a correction for heart rate was applied using the Bazett formula (Sagie et al, 1992): p QTc ¼ QT= RR In this formula, RR is the interval between two subsequent R waves. The Bazett formula is the most frequently ...
The Myth of QT Shortening by Weight Loss and Physical Training in Obese Subjects With Coronary Heart Disease This study aims to describe the changes that a period of low-calorie diet and physical training determines in heart rate and in corrected QT (QTc) interval... LA Gondoni,AM Titon,M...
Multi-targeted vascular endothelial growth factor receptor (VEGFR) tyrosine kinase inhibitors (TKIs) are known to cause cardiac toxicity, but the relative risk (RR) of QTc interval prolongation and serious arrhythmias associated with them are not reporte
