Atrial Fibrillation (AFib) Awareness Month 2023

September is National Atrial Fibrillation (AFib) Awareness Month. Join HRS and Sanofi this September and beyond as we seek to improve the lives of those affected by AFib.

Together, we can make a difference by raising awareness, promoting early detection, and ensuring access to accurate information. 



Atrial Fibrillation, AFib for short, is a serious condition that affects the rhythm of your heart, causing it to beat irregularly. This irregular heartbeat can manifest in various ways, including beating too fast, switching between fast and slow rhythms, or skipping beats altogether.
AFib is the most common type of cardiac arrhythmia. It has a significant global impact, affecting nearly 40 million individuals worldwide and 6 million people in the United States alone.1 The Centers for Disease Control and Prevention predict that 12.1 million people in the U.S. will have AFib by 2030.2
Today, the risk of developing AFib is a concern for approximately 1 in 4 adults over 40 years old.2 Despite this growing prevalence, many individuals remain unaware of the symptoms associated with AFib, the range of available treatment options, and the critical importance of seeking early treatment to prevent disease progression.
In honor of AFib Awareness Month and beyond, HRS, in collaboration with our partner Sanofi, will provide comprehensive and easily accessible information about AFib, its causes, symptoms, and potential complications.

Explore these expert-developed AFib resources below to empower yourself with the knowledge needed to make informed decisions about your or your loved one's heart health journey and overall well-being.

Heart Rhythm Disorders
Millions of people experience irregular or abnormal heartbeats, called arrhythmias, at some point in their lives. Most of the time, they are harmless and happen in healthy people free of heart disease. However, some abnormal heart rhythms can be serious or even deadly. Having other types of heart disease can also increase the risk of arrhythmias.
Pediatrics and Congenital Heart Disease (CHD)
This section is for pediatric patients and families living with heart rhythm disorders and heart rhythm disorders related to congenital heart disease (CHD).
Early Warning Signs
If you are experiencing a racing, pounding, rumbling or flopping feeling in your chest or if you have been fainting, having repeated dizzy spells, feeling lightheaded or you are extremely fatigued, it's time to see a doctor to discuss your heart health.
Common Treatments
Learning about the underlying cause of any heart rhythm disorder provides the basis for selecting the best treatment plan. Information and knowledge about care options, and their risks and benefits help you work with your health care provider to make the best choices.
Since other heart disorders increase the risk of developing abnormal heart rhythms, lifestyle changes often are recommended. Living a “heart healthy” lifestyle can ease the symptoms experienced with heart rhythm disorders and other heart disorders, and can be beneficial to overall patient health.
The Normal Heart
The heart is a fist-sized muscle that pumps blood through the body 24 hours a day, 365 days a year, without rest. The normal heart is made up of four parts: two atria on the top of the heart (right atrium and left atrium), and two ventricles (right ventricle and left ventricle) which are the muscular chambers on the bottom of the heart that provide the major power to pump blood.
