i think it's PR segment and not the PR interval because PR segment contains a straight line right after P wave offset which works best as a baseline for QRS complex, you can also use ST segment for the same purpose
It means you are tachycardic or heart beating fast.
It means you are tachycardic or heart beating fast.
PR (Pulse Rate) intervals are measured by using the gap between the beginning of the P wave (the excitation of the atria) and the beginning of the QRS , a typical deflection seen on an ECG (Electrocardiogram).
The ECG of a patient with hypocalcemia will show q number of different distinct patterns. The ECG will show a T wave that is inverted and flattened, a prolongation of the QT interval, a narrowing of the QRS complex, a prolonged ST and ST depression, a reduction in the PR interval, and a prominent U wave.
$0.50-$1.00
PR = 110 because... P = 10, Q = 2... therefore R = 11
Pr{z<=1.0805}~=0.86

Current average value of a certified PR-65 1894 Barber dime is $1,400.00.
If the value given in the table for Z = z is k: that is, pr(Z > z) is 1 - k, then the two-tailed probability of observing a value which is at least as extreme, ie Pr(|Z| > z) is 0.5*(1-k).
In all likelihood, it stands for Probability. For example, Pr(X < 3) is a way of writing "Probability that a random variable, X, takes a value less than 3".
