Complications
Sometimes atrial fibrillation can lead to the following complications: Stroke. In atrial fibrillation, the chaotic rhythm may cause blood to pool in your atria and form clots.

The risk of stroke in atrial fibrillation depends on your age (you have a higher risk as you age) and on whether you have high blood pressure, diabetes, or a history of heart failure or previous stroke, and other factors. Medications such as blood thinners can greatly lower your risk of stroke or damage to other organs caused by blood clots. Heart failure. Atrial fibrillation, especially...

Prevention
There are some things you can do to try to prevent recurrent spells of atrial fibrillation. You may need to reduce or eliminate caffeinated and alcoholic beverages from your diet, because they can sometimes trigger an episode of atrial fibrillation. It's also important to be careful when taking over-the-counter (OTC) medications. Some, such as cold medicines containing pseudoephedrine, contain stimulants that can trigger atrial fibrillation. Also, some OTC medications can have dangerous interactions with anti-arrhythmic medications.
