WebDec 2, 2024 · P wave morphology. The P wave typically has a different morphology and axis to the sinus P waves; PACs arising close to the AV node (“low atrial” ectopics) cause retrograde activation of the atria, producing an inverted P wave with a relatively short PR interval ≥ 120 ms (PR interval < 120 ms is classified as a PJC); The abnormal P wave may … WebNov 9, 2024 · If the P is inverted with a normal PR interval (>0.12s), it’s taking a longer time to reach the ventricles than a junctional P wave would (<0.12s).
