Atrial fibrillation is one of the most common types of heart rhythm disorder (arrhythmia), affecting more than 2 million people nationwide. It occurs when the atria, or upper chambers of the heart, fail to beat in a synchronized manner. As a result, the heart doesn't squeeze normally. In many patients with atrial fibrillation, the heart beats too quickly.

Atrial Fibrillation: What You Need to Know


You can prevent recurrent spells of atrial fibrillation by:

  • Drinking less or no caffeinated and alcoholic beverages
  • Talking with your doctor about over-the-counter (OTC) medications:
    • Those that contain pseudoephedrine, which acts as a stimulant, can trigger atrial fibrillation
    • Some OTC medications can have dangerous interactions with anti-arrhythmic medications

Atrial Fibrillation: Managing Your Symptoms


What is Atrial Fibrillation?

Normally, the heart beats in a strong, stable rhythm. In patients with atrial fibrillation, a problem with the heart's electrical system causes the two upper parts of the heart, the atria, to quiver, or fibrillate.

The quivering upsets the normal rhythm between the atria and the lower parts of the heart, the ventricles. And the ventricles may beat fast and without a regular rhythm.

Atrial fibrillation is dangerous because if the heartbeat is irregular blood can collect, or pool, in the atria. Pooled blood is more likely to form clots. Clots can travel to the brain, block blood flow and cause a stroke.

Atrial fibrillation can also lead to congestive heart failure. Your atrial fibrillation may be occasional (paroxysmal atrial fibrillation) where your symptoms may come and go, last for a few minutes to hours and then stop on their own. Chronic atrial fibrillation is when your heart rhythm is always abnormal.

Atrial fibrillation symptoms include:

  • Heart palpitations, which feel like a fluttering or flopping in your chest or a racing, pounding or uneven heartbeat
  • Shortness of breath
  • Weakness
  • Decreased blood pressure
  • Dizziness
  • Confusion
  • Chest pain
  • Passing out (fainting)

Several factors can increase your risk of developing atrial fibrillation, including:

  • Age: Risk increases as you age
  • Family history: Parent, brother or sister with atrial fibrillation
  • Heart disease, heart attack or heart surgery
  • High blood pressure
  • Chronic medical conditions such as thyroid problems or sleep apnea
  • Drinking alcohol, particularly a large amount at one time (binge drinking)
