Talk to your cardiologist. I assume you are on digoxin? As long as you don't stress
your heart too much it should stay in rhythm. But stress means different things to different hearts. I could lift weights without having a problem as long as my dig level is up. If it's down too low, I could go into AF just by bending over to pick something up. It just depends on what your heart can take and if you maintain a sinus rhythm
on meds. Everyone is different and everyone's heart has a different stress point.
