Overview
A retrograde P wave is a an atrial P wave on the elctrocardiogram that is inverted or upside down most often in leads II, III or aVF.
Causes
- Low atrial focus to the rhythm (narrow QRS complex present)
- Retrograde or backward electrical conduction from the AV node or ventricles to the atria (a wide QRS complex may or may not be present)
- AV nodal reentry tachycardia
