Web2 dec. 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 … Web24 jan. 2015 · A mid junctional rhythm will have no visible P waves as the P wave will be within the QRS due to simultaneous activation of the atria and ventricles.
