Atrial Fibrillation Awareness Month

Atrial Fibrillation Awareness Month is observed every September to raise awareness about atrial fibrillation, often called AFib or AF. AFib is a common heart rhythm disorder that can cause an irregular, too fast, or sometimes too slow heartbeat. The month encourages people to learn the symptoms, understand the risks, and speak with a qualified healthcare professional if they notice warning signs.

History of Atrial Fibrillation Awareness Month

Atrial Fibrillation Awareness Month is promoted by organizations such as the Heart Rhythm Society and the American Heart Association to improve education, early detection, and patient care. The observance focuses on helping people understand AFib, recognize possible symptoms, and learn why treatment and follow-up care matter.

AFib happens when the heart’s upper chambers, called the atria, do not beat in a normal coordinated rhythm. Blood may not move through the heart as well as it should, which can increase the risk of blood clots and stroke. Some people have brief episodes, while others have persistent or permanent AFib.

Treatment depends on a person’s age, symptoms, stroke risk, other health conditions, and how long AFib has been present. Care may include medicines to control heart rate or rhythm, blood-thinning medicine to reduce clot risk, lifestyle changes, cardioversion, catheter ablation, surgery, or other procedures.

Ways to Observe Atrial Fibrillation Awareness Month

Atrial Fibrillation Awareness Month can be observed by learning the signs and risk factors of AFib and sharing reliable information with family, friends, and community members. People who notice an irregular heartbeat, unexplained fatigue, dizziness, shortness of breath, or palpitations should discuss these symptoms with a healthcare professional.

The month is also a good time to support people living with AFib.
