What are they doing for the anemia? Anemia can cause your heart to work harder but I have no idea if that causes PVC's and PAC's. With menopause, my palpitations stopped (though starting 14 years later I had afib occasionally). I wonder if a sudden hormonal change from the hysterectomy has triggered this increase in palpitations and if your body adjusts over time, things will get better.

I was always told there were "benign" and MD's did not understand how scary they can be. Have you worn a holter monitor? I assume so.

I hope this gets better for you. I found that tai chi helped me quite a bit. I am also careful not to eat after 5pm, since late eating was a trigger. Good luck!
