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 diabetic pet is considered regulated when its blood glucose levels remain within an acceptable range on a regular basis. Acceptable levels for dogs are between 5 and 10 mmol/L or 90 to 180 mg/dL. [64] [65] The range is wider for diabetic animals than non-diabetics, because insulin injections cannot replicate the accuracy of a working pancreas.
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]
The QTc is less than 450 ms in 95% of normal males, and less than 460 ms in 95% of normal females. LQTS is suggested if the QTc is longer than these cutoffs. However, as 5% of normal people also fall into this category, some suggest cutoffs of 470 and 480 ms for males and females respectively, corresponding with the 99th centiles of normal values.

So what we have to do is find the corrected QT interval, or QTc, at the different rate so that you can compare it to the QT interval at 60 beats per minute. Even though there are several formulas you can use, the Bazett’s formula’s probably the simplest, where the corrected QT interval equals the QT interval in milliseconds divided by the ...
Why do dogs need so much sleep? During a typical night, adult humans spend around 20-25% of their total sleep in REM (Rapid Eye Movement) stage, a percentage that is even higher in infants and ...
