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 pregnant women, and it is longer in older persons. Prolonged PR Interval: Prolongation of the PR interval above 0.20 s (5 small squares) is called first degree AV block. WebFigure 1. Electrode positions on an ECG (EKG). When electrical activity (or depolarisation) travels towards a lead, the deflection is net positive. When the activity travels away from the lead the deflection is net negative.

"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.
