Hi there- I have the same thing going on- I can see my pulse - it is very strong-it moves both breasts and shakes my stomach,this started 3 yrs ago-Dr said it was anxiety and upped my xanax
dosage. But I think this came from Levaquin (an antibiotic). It is very scary to me-had 2 echoes,holter monitor,event monitor,3-4 ekgs,an an aortic ultrasound.Everything came back normal.I was on 4 mg of xanax a day and still saw the heartbeat-sooooo,not anxiety.
