A normal heartbeat on ECG will show the timing of the top and lower chambers. The right and left atria or upper chambers make the first wave called a “P wave" — following a flat line when the electrical impulse goes to the bottom chambers. The right and left bottom chambers or ventricles make the next wave called a “QRS complex."

The PR (or PQ) interval starts at the start of the P wave and ends at the start of the QRS. It denotes the conduction of the impulse from the upper part of the atrium to the ventricle. The QRS interval covers the QRS complex from beginning to Heart rate is usually normal, but slow in telemetered monkeys to 80 beats per minute. The pauses between RR intervals are not greater than two normal RR intervals. The irregularity in RR intervals is due to changes in vagal tone secondary to respiration, but it is not as great as in other species, such as the dog.

2020-11-01 This interval should be determined in the ECG lead where it is longest. Normal intervals are < 460 ms for women and < 450 ms for men. But QT values are heart-rate dependent and can vary from 270 ms at a heart rate of 150 beats/min to 500 ms at a heart rate of 40 beats/min. Corrected QT interval 2017-10-29 Table 1 – ECG analysis PR interval Figure 6 - Normal sinus rhythm 1.

• PR Interval: Normal and consistent (0.12-0.2 sec). The normal PR interval is from 0.12-0.2 seconds and is measured on the EKG from the beginning of the P wave to the beginning of the QRS complex. In this ECG, RR intervals vary considerably.

It's normally 0.12-0.20 seconds, which is three to five little boxes, since each little box is 0.04 seconds. Therefore, the PR interval shown is about four boxes or 0.16
