I am a very healthy female, 60 yrs. old, and recently diagnosed with Afib and am scheduled for a catheter ablation. I honestly think I may have brought this on by continuing to train hard (like HIIT training at near 100% MHR) after breaking my ribs in a mountain bike fall. Certainly my lifestyle will likely change post ablation, but after I am off the drugs and blood thinners and my heart has "healed", what are the chances that I can backpack, cycle up hills, and teach fitness classes like I have been before (with obvious modifications and monitoring I guess) (?) My husband is ready to chain me to the couch for the rest of my life...I'm needing a ray of hope that although I may not be able to go "balls to the walls", that I can once again be active without causing further damage. Any experiences out there?
