How long the condition lasts depends on the cause. Atrial fibrillation caused by a treatable condition may go away when the condition is treated.
However, atrial fibrillation is often a lifelong condition. This is more likely when it has no known cause or results from a long-standing cardiac disorder.
Atrial fibrillation resulting from coronary artery disease can be prevented. Take these actions to reduce your risk:
Eat a low-fat diet.
Control cholesterol and high blood pressure.
Do not drink more than two alcoholic drinks per day.
Control your weight.
Get regular exercise.
Some causes of atrial fibrillation cannot be prevented.
