Key result
Retrograde ventricular beats in complete AV block produce inverted inferior P waves and positive aVR.
Why the study?
Retrograde conduction of automatic ventricular beats in complete auriculoventricular block was long considered impossible but recent data have changed this view.

May aid ECG interpretation in complete AV block; leaves open its prevalence and clinical implications.
Contrary to historical belief, retrograde conduction in complete A-V block is possible and can be identified by specific abnormal P wave patterns on ECG following automatic ventricular beats.
N.C. Louvros (1965) conducted a review in Complete auriculoventricular (A-V) block. Retrograde conduction of automatic ventricular beats was evaluated. Retrograde conduction of automatic ventricular beats in complete A-V block produces abnormal P waves that are inverted in leads II, III, and aVF and positive in aVR.
