planning a trip to machupichu Peru, altitude 10,000 plus feet, I don t suffer from atrial fribilation but I have had two episodes of it in my life. Iam 59 years old, weigh 155 pounds, and run 3 miles 3/4 times a week in less than 29 minutes. I also suffer from mild/moderate aortic insufficiency, but totally asyntomatic. Can this trip cause another afib event because of the altitude.? I have normal blood pressure and taking no medication,
