PJCs have the following features: Narrow QRS complex, either (1) without a preceding P wave or (2) with a retrograde P wave which may appear before, during, or after the QRS complex. If before, there is a short PR interval of < 120 ms and the “retrograde” P waves are usually inverted in leads II, III and aVF.
