I'm 4 days post op and still experience some high heart rate. I can't tell if it is anxiety or not

Make sure that you are getting all your fluids in. Dehydration can cause you to have a rapid heart rate. This happened to me as well and I had to get some pedialyte

Agree most likely dehydration also some meds cause some people that. My heart is very sensative to all kinds of things send it it thumping away.

Track your HR hourly over a 24 hr period. If it stays high (over 120 bpm) for more than a couple of hours, contact your surgeon. It can be a sign of a leak. Not trying to freak you out, but my hubby was sleeved Wednesday and his HR was high after surgery, so his surgeon did a CT scan and two barium swallows before we could leave just to make sure there wasn't a leak. There wasn't, thank goodness - they think it was because he was off his blood pressure meds for a day or two - once he started back on them, his HR went down.
