ICU/EKG: Junctional Rhythm, Atrial lead EKG

Rhythm strip from Surface Leads:

What is the rhythm? Atrial lead is on V1.
How would you differentiate between Sinus rhythm with First degree AV block from Junctional rhythm with retrograde P, in this patient? (14 month old, s/p TOF repair, Postop day #1)
