Atrial fibrillation is an irregular heartbeat that can cause blood clots and serious health issues. Symptoms include chest pain, fatigue, dizziness, and shortness of breath. Consult your doctor if you think you may have it. Online research can help you prepare to meet with your doctor.
What Is Atrial Fibrillation?
Atrial fibrillation (AFib) is a heart condition characterized by an irregular and rapid heart rhythm.1 It occurs when the heart’s upper chambers, known as the atria, beat chaotically and out of sync with the lower chambers, called the ventricles. This disruption in the heart’s electrical signals leads to an irregular heart rate. It can increase the risk of serious health complications, including stroke, heart failure, and blood clots.
Serious Health Issues
The irregular heart rhythm associated with AFib can have several adverse effects on the body. One of the most significant risks is the formation of blood clots in the heart. The chaotic electrical signals in the atria can cause blood to pool and stagnate, increasing the likelihood of clot formation. These clots can then travel through the bloodstream and block arteries in the brain, leading to a stroke.
AFib also increases the risk of heart failure. The rapid and irregular heart rate can weaken the heart muscle over time, making it less effective at pumping blood throughout the body. This can lead to a buildup of fluid in the lungs and other organs, causing shortness of breath, fatigue, and swelling.
Symptoms of Atrial Fibrillation
AFib can manifest with various symptoms, but some individuals may experience no noticeable symptoms at all. Common symptoms of AFib include:
- Chest pain or discomfort2
- Palpitations or a racing heart
- Fatigue or weakness
- Dizziness or lightheadedness
- Shortness of breath
- Confusion or memory loss
- Difficulty exercising
It is important to note that these symptoms can also be associated with other medical conditions, so it is crucial to consult with a healthcare professional for proper diagnosis and management.

Recognizing the symptoms — ranging from chest pain and palpitations to fatigue and shortness of breath — is crucial for timely medical consultation and intervention. Although some individuals may not exhibit noticeable symptoms, those experiencing any relevant signs should seek expert medical advice. As AFib can have serious repercussions on overall health, it is imperative for individuals to be proactive in understanding their symptoms and to consult healthcare providers for proper diagnosis and effective management of this complex heart condition.
