WebFeb 4, 2024 · 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. PR interval < 120 ms suggests pre-excitation (the presence of an accessory pathway between the atria and ventricles) or AV nodal (junctional) rhythm.

WebJan 17, 2024 · Increased or decreased P waves can indicate problems with the potassium ion concentration in the body that will alter nerve activity.
