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).

How do you calculate the PR interval?
RR interval 795 QRS interval 140 What is PR interval??
What level of the conduction system does the PR interval result from a delay in?
Sa node
What is the difference between PR segment an PR interval in EKG?
The difference between intervals and segment is that intervals include the waves,and segments don't.
Can a variable measured at the interval or ratio level can have more than one arithmetic mean?
A variable measured at the interval or ratio level can have more than one arithmetic mean.
What is the z value for 86 percent confidence interval estimation?
Pr{z<=1.0805}~=0.86
If PQ 20 and QR 22 Then what does PR equal?
PR = 110 because... P = 10, Q = 2... therefore R = 11

Speed measured in an infinately small time interval?
instantaneous speed
Is absolute zero point measured by interval or ratio scale?
Ratio
What is baseline in ECG?
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
When calculating the mean the researcher should use data measured at which level?
interval
Is Electrocardiography invasive?
No
