Symptoms of Atrial fibrillation

The most obvious symptom of atrial fibrillation is a completely irregular but fast heart-beat rate, usually over 140 beats per minute. In the early stages, affected people have palpitations and are aware of the irregularity of the heart’s action, but with time, if the condition persists, as it commonly does, most of them become accustomed to the symptom and fail to notice it.

Atrial fibrillation inevitably reduces the efficiency and performance of the heart. Consequences of this may include inadequate supply of blood to the heart, low blood pressure, disorder of the heart muscle, or even heart failure.
