A normal corrected QT interval (QTc) duration is typically considered under 430 milliseconds for an adult male and under 450 milliseconds for an adult female after correction. If you want to determine the QTc of a patient, you can use the Omni QTc calculator. What is QTc prolongation? A pro...
Objective: Present study is undertaken to understand genesis of variability in QTC interval in healthy subjects as per age, sex and weight parameters and planning preventive measures for any abnormal findings.Materials and methods: 315 healthy normotensive healthy subjects (male=179, female=136) in ...

We hypothesized that female gender in people with mental disorders could be a risk factor of QTc prolongation. In this research, we focused on gender difference in QTc interval distribution and examined related factors of the QTc prolongation of people with mental disorders....
In the presence of relative hypokalaemia, hypertensive patients with LVH showed more QTc dispersion (85.7 ± 15.5 ms) and a greater tendency for complex ventricular arrhythmias (100% grade ⩾3 Lown’s score) compared to those with LVH and normal serum potassium levels (64.1 ±...
(Italy) reported that a heart rate-cor- rected QT time according to the Bazett formula (QTc-Bazett) in former extremely low birth weight (ELBW) infants in young adulthood (mean age 23 years) was at the upper limit of the normal range and correlated with gestational age. Relevant for...
