I got a holter test done came back that my heart was adding beats and i feel my heart beating on my back when laying down and i can see my pulse on top of my wrist is this dangerous?

Depends on rhythms : It all depends on what the Holter says. Did your symptoms (back heart beat and wrist pulse) correlate with an abnormal rhythm on the Holter? (Hopefully you kept a symptom.diary when wearing the Holter) If the underlying rhythm I'd dangerous (VTACH or other) then a Cardiologist consult is needed. If the underlying rhythm is aberrant it could still be benign (atrial tach or atrial flutter). TTYD.
