PR Interval • LITFL • ECG Library Basics
Feb 4, 2021 · PR Interval. The PR interval is the time from the onset of the P wave to the start of the QRS complex. It reflects conduction through the AV node. The normal PR interval is between 120 – 200 ms (0.12-0.20s) in duration (three to five small squares).
Step 4 PR interval (PRi) - EKG Lesson #318
Nov 8, 2021 · Step 4 PR interval (PRi) - Cardiac Rhythms. Description. Measurement of the PR interval reflects the amount of time from the beginning of atrial depolarization to the beginning of ventricular depolarization. Plainly stated, PR interval measurement is from the beginning of the P wave to the beginning of the QRS complex.

PRI and QRS Measurements - University of New Mexico
The PRI measurement is from the point where the Pwave deflects from isoelectric to the beginning of the Qwave. If no Qwave is present, the end of the PRI is at the beginning of the Rwave. The QRS is from the beginning of the Qwave (or Rwave if no Qwave is present) to where the Swave returns to isoelectric (which is the J point).
