An "abnormal" QTc in males is a QTc above 450 ms; and, in females, above 470 ms. [17] If there is not a very high or low heart rate, the upper limits of QT can roughly be estimated by taking QT = QTc at a heart rate of 60 beats per minute (bpm), and subtracting 0.02 s from QT for every 10 bpm increase in heart rate.
The value for a normal QT interval is similar in males and females from birth up to adolescence. During infancy, a normal QTc is defined as 400 ± 20 milliseconds. Before puberty, the 99th percentile of QTc values is 460 milliseconds. After puberty, this value increases to 470 milliseconds in males and 480 milliseconds in females. [citation needed]
Genotype and QTc interval duration are the strongest predictors of outcome for patients with LQTS. [ 17 ] [ 18 ] 2022 European Society of Cardiology clinical practice guidelines [ 44 ] have endorsed the use of independently validated risk score calculator, called 1-2-3-LQTS-Risk Calculator, [ 45 ] which allows to calculate individual 5-year ...
A study published last year found that a healthy diet could increase lifespan by up to 10 years, and Nathan K. LeBrasseur, a physiologist at Mayo Clinic, previously told BI that spending just 3% ...

When it comes to losing weight, there are no shortage of unproven recommendations to choose from: fad diets like the carnivore diet or GOLO diet; juice cleanses and vitamin injections; plus a host ...
The tattooed corpse of a woman was found bizarrely stuffed in a refrigerator dumped in some New Jersey woods — and cops say they need the public’s help identifying her.
The Well-Being Index is an online self-assessment tool invented by researchers at Mayo Clinic that measures mental distress and well-being in seven-nine items. [1] [2] The Well-Being Index is an anonymous tool that allows participants to reassess on a monthly basis, track their well-being scores over time, compare their results to peers' and national averages, and access customized resources ...
