Which is a common symptom of atrial fibrillation?

Palpitations are indeed a common symptom of atrial fibrillation. This sensation refers to an awareness of an irregular or rapid heartbeat, which often feels like fluttering, pounding, or racing in the chest. Atrial fibrillation causes the heart's electrical signals to become disorganized, leading to an erratic heartbeat that can be alarming and noticeable to the individual experiencing it.

While some patients may also experience other symptoms such as chest pain or shortness of breath during physical activity, palpitations are more closely associated with the irregular rhythm characteristic of atrial fibrillation. High fever, on the other hand, is not typically connected to this condition and usually indicates an infection or inflammatory process unrelated to atrial fibrillation.
