Pr segment vs pr interval

The morphology of the ST segment (shape, and deviation from the isoelectric baseline that is usually defined as the amplitude of the PR segment) is important. It is nevertheless important to identify it for that reason. Based on the presence or absence of PR interval shortening after single blocked complexes, patients with narrow-complex non-Wenckebach patterns could be separated into a pseudo-Mobitz II group of 16 patients (greater than or equal to 20 msec of PR shortening after the blocked complex) and a classic Mobitz II group of four patients (constant PR interval).

Overview of EKG Training.

P-R interval is measured from the onset of the P to the onset of the QRS Normal P-R: from 0.12 – 0.20 s (between 3 and 5 little boxes) May be normal up to 0.22 s with sinus bradycardia Diffuse concave upward ST segment elevation 2.

Thus the PR interval can be shorter than, longer than, or equal to the RP interval. The PR interval can also be equal to the RR, and the P wave may fall inside the preceding QRS, thus mimicking typical AVNRT. The PQ interval ( PR interval) represents the time for conduction from the SA node across the AV node and His-Purkinje system. Normal values for the PQ interval in horses vary considerably because of high resting parasympathetic tone.
