Which symptom is commonly associated with atrial fibrillation?

Atrial fibrillation (AF) commonly presents with a variety of symptoms due to its effect on the heart's rhythm and its impact on blood flow. The correct answer encompasses all listed symptoms—chest pain, shortness of breath, and fatigue—because patients with AF may experience any or all of these manifestations.

Chest pain can occur in AF, especially if the irregular pulse leads to inadequate blood supply to the heart muscle. The heart's inability to pump effectively during AF can also contribute to feelings of pressure or discomfort in the chest.

Shortness of breath is frequently reported because AF can lead to decreased cardiac output and pulmonary congestion. The irregular heartbeat may cause the heart to work harder, which can result in difficulty breathing, especially during exertion or when lying flat.

Fatigue is another common symptom because the inefficient heart function can leave patients feeling tired or exhausted. The irregular rhythm and potential for rapid heart rates during AF can exhaust the body's energy reserves, leading to a general sense of lethargy.

Given these connections, it is clear that atrial fibrillation can lead to a wide range of symptoms, making it important for healthcare providers to assess all potential signs when diagnosing and managing this condition.
