AFib: Other Interesting Stuff.
Whats on this page:
Endurance athletes have more AFib, especially when they are older.
There is no question that highly trained athletes are healthier, live longer. are thinner, and often feel better than more sedentary folks.
There is also no question that endurance athletes who have been at it a long time, particularly after age 50, have more AFib.
The relationship to exercise is direct. The athletes in more competitions and the winners of competitions have more AFib than the less vigorously training athletes,
Exercise is good and healthy, but just like it can be hard on your knees, it can be bad for AFib.
Treaments for AFib, particulary ablation, help athletes continue there sports.
Does high altitude effect AFib?
Probably it does, but there isn't a lot of proof.
There are several ways that high altitude can effect heart arrhythmias.
Increased Sympathetic Tone.
Increased sympathetic tone is an adrenaline like effect that results from lower oxygen levels at altitude. This stimulant effect can aggrevate heart arrhythmias.
Sleep Apnea is worse at altitude.
Sleep apnea is much worse at higher altitude , particularly central sleep apnea which is highly related to AFib.
If you plan to exercise at altitude, make sure you are in good enough shape. Everything is harder with less oxygen.
If you have sleep apnea it will be worse at altitude, be sure that you stay on treatment.
If you have a heart condition have it evaluated to see if you can deal with the added stress of high altitude and have beta blocker therapy if needed to deal with the increased sympathetic tone.
