It is possible that your high HR is the result of anemia, which often happens after such surgery, especially if you had the open heart w/bypass procedure. Ask to have your blood tested for low iron to see if that could be the cause. You can expect a higher HR for weeks after such surgery, but my experience was that it would sometimes be around 90 at rest instead of high 70s. Now, 9+ years later at age 69, resting HR is back to 55-60.

I do not know what specifically the Maze IV is, a robotic procedure to do a Maze procedure on the heart?
I had a "mini maze" done several years ago when I was "open" for a valve repair. The maze was done to cure atrial fibrillation. It didn't hold, I went back into AFib about 30 days after the procedure. The first sign I saw following surgery, and before I had my first follow up visit with my Cardiologist my resting HR was about 130. My cardio confirmed I was back in AFib and some Atrial Flutter too. I have been living with the AFib since that time with mediation to reduce clot formation and to lower my HR. I take both a beta blocker and a calcium channel blocker and my resting HR is now in the 70s... I think in the high 60s when sleeping or really at rest.
I agree a resting HR of 120 is too high.
