Bigeminy of PVC's in a young adolescent?

Question

What would cause bigeminy of PVC's in a young adolescent?

Only hx is hemophilia.
Recently recieved clotting factor.
No cardiac history.
Recent trauma - fell from standing height
Previous complaint of shoulder pain, no pain right now.
12 lead - negative.
Currently on O2 @2 LPM
Asymptomatic, no chest pain or SOB.
PVC's are non perfusing.
Pt's HR is about 40, if you don't count the non-perfusing beats.

I'm at a loss for what might have caused the PVC's.

Thanks!

Not to sound unappreciative, but I'm looking for answers from doctors, nurses, other paramedics, etc.

Answer 1

I had PVC's that were caused by caffine. make sure that there is no use of energy pills.
