I hope you've already seen your doctor. It, very well could be atrial fibrillation. A-fib is common after AVR. I had a few hour of it the second day after AVR. It is treatable, but you do need to see a doctor.

Have you had a lot of caffeine in the last 24 hours? I would notice and still do feel my heart beating faster when I have caffeine after 2:00. I am 4 month post op. I stayed away from caffeine for 3 months after surgery. After that I started with 1/2 decaf. Coffee. Hope this helps
