Symptoms of atrial fibrillation

Atrial fibrillation (also known as AF or AFib) is the most common type of arrhythmia (irregular heartbeat or heart rhythm). Symptoms of AF can vary. You may experience symptoms or you may not. You can sometimes feel AF symptoms, but at other times not feel it at all.

Atrial fibrillation can occur once in a while, or it may be present continuously.

Symptoms of AF include:

• palpitations - the most common symptom, typically experienced as a rapid thumping in the chest
• irregular and rapid heartbeat
• chest pain, discomfort, or tightness
• dizziness, lightheadedness, or fainting
• fatigue
• shortness of breath or difficulty breathing, especially with exertion or anxiety
• sweating
• nausea
• becoming easily tired after exercising or being active
• weakness

How often and the length of time these symptoms occur can vary, as well as how severe the symptoms are. Some people do not feel any symptoms at all and feel fine, while others have debilitating symptoms that severely affects their quality of life.

Whether or not you feel symptoms, atrial fibrillation is a serious condition that should not be ignored. The good news is that you can live an active, healthy life with appropriate treatment.
