Atrial Fibrillation

What is Atrial Fibrillation?

Atrial Fibrillation, also referred to as AFib, is an irregular and often rapid heartbeat that is commonly described as a “fluttering” or “pounding” sensation. If left untreated, it can lead to blood clots, heart failure, stroke and other heart-related complications. It’s one of the most common heart rhythm problems among adults in the U.S., impacting about 9% of people age 65 or older and 2% of people under age 65. It’s common in people who have other heart conditions, such as atherosclerosis and high blood pressure (hypertension).

What are the Symptoms of Atrial Fibrillation?

Although atrial fibrillation doesn’t always present symptoms, some of its more common symptoms include:

  • Chest pain
  • Dizziness
  • Fatigue
  • Lightheadedness
  • Sensations of a fluttering or pounding heartbeat
  • Shortness of breath
  • Weakness
