I was diagnosed with AF 2 years ago - im not on any related medication other than statins. I was told that as long as the AF does not affect my daily living then no action is required. I am 53.
I have since continued to go to the gym 5 days per week doing fitness classes. Recently while on the x trainer while experiencing AF I have recorded my heart rate during the workout racing up to and beyond 200. I can sometimes control this somewhat by reducing my work rate to walking pace. It seems to be happening more often, is this something to be concerned about? should I be going back to see my GP?
