Occasional atrial fibrillation can be serious. While many people do not experience or feel symptoms of arrhythmia, complications can result if the condition is left untreated. For example, stroke and heart failure, both life-threatening events, can occur.

Douglas Severance, Family Medicine, answeredAny type of atrial fibrillation has the potential to be serious since the risk of blood clots and stroke increases. With occasional atrial fibrillation, you may notice the arrhythmia for a few minutes and then it may go away. Your doctor may not be able to detect the arrhythmia with a physical examination or tests. Also, with occasional atrial fibrillation, the heart may go back to normal rhythm on its own.
If the atrial fibrillation persists, your doctor may prescribe anti-coagulant drugs such as warfarin (Coumadin) to prevent blood clots and stroke. Other medications may be used to slow the heart rate and to convert the rhythm to normal sinus rhythm. Talk to your doctor if you have occasional atrial fibrillation to see how certain lifestyle changes may also help stop this arrhythmia. This may include avoiding caffeine, smoking, alcohol and stress.
