I love to hike and enjoy the mountains, however, since my AFib diagnosis I can't travel to high elevations or hike up hills without going into AFib. I experience dyspnea, dizziness, and fatigue when I push my heart too hard. I wear a continuous oximeter to measure my oxygen level when hiking, my oximeter will alarm when my oxygen level drops below 90%, When I travel over 5000 feet, I need extra oxygen. I live at 4500 feet and my heart does fine jogging 5 miles on flat surfaces without oxygen.

The VO2 Max test is non invasive treadmill test your Cardiologist can order that may be very helpful to assess your heart's response to exercise and your oxygen update. I went into AFib after this test three years ago. I have modified my exercise routine and I have not experienced an AFib episode in 2 years. I take a low dose of a statin, but no other heart medications.

I also recommended getting a smart watch. I always wear my Apple Watch because my heart can go into AFib without any symptoms at a low heart rate. My watch will send out an alert.

The "AFib Cure " book by Dr John Day is also a great reference for lifestyle changes and treatment options.
