WebNov 22, 2024 · In adults the normal PR interval is 0.12 s to 0.20 s (3 to 5 small squares ). Normal PR interval (0.14 s). It is generally shorter in children (see pediatric EKG) and in … WebThe 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). If the PR interval is > 200 ms, first degree heart block is said to be present.
