Heart Surgery Can Be a Trigger
One of the risks of having open-heart surgery or coronary artery bypass graft surgery (CABG) is atrial fibrillation. Your doctor will work to control or correct this as it can lead to other complications.
Lone AFib
Atrial fibrillation that happens in younger people (less than 60 years old), without an obvious cause is called lone AFib. Lone AFib can be triggered by exercise, eating, sleeping, and alcohol. Sometimes it comes and goes on its own and may not need immediate treatment. Consult your doctor.
