Can atrial fibrillation be triggered by flying?

AF and flying: It is unlikely in commercial airlines that flying can trigger af. Oxygen levels are kept at < 8000 feet as if on the ground. It can happen if there is additional significant lung disease thereby reducing o2 levels in the blood. Majority of patients with af due not have an obvious consistent trigger for their episodes.

Atrial fibrillation: Flying in a commercial aircraft pressurizes to about 8000ft, this level doesn't cause hypoxia so unlikely to be a trigger unless something else like anxiety or other stress supervenes. If something goes on stressful in the aircraft, one could imagine a trigger possibility. I have seen patients get a gas bubble in their GI tract at altitude and be anxious for instance.
