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 …
