Which symptom is commonly associated with atrial fibrillation?

Atrial fibrillation (AFib) is characterized by irregular and often rapid heart rhythm, which can lead to various symptoms due to the heart’s inability to pump blood efficiently. Shortness of breath is a commonly reported symptom among individuals with AFib. This occurs because the disorganized electrical signals in the heart can lead to decreased cardiac output, resulting in reduced oxygen-rich blood reaching the lungs and other parts of the body. As a result, patients may experience difficulty in breathing, especially during physical activity or exertion.

While chest pain, nausea, and fatigue can also occur in some individuals with AFib, shortness of breath tends to be one of the more prominent and immediate symptoms that prompt patients to seek medical attention. The connection between AFib and respiratory symptoms highlights the importance of monitoring for signs of this condition, particularly in patients with underlying heart disease or other risk factors.
