Weakness
Atrial fibrillation would cause your heart to pump more quickly, which reduces the amount of oxygen in each flow to other body parts. Thus, your body cells will not get sufficient nutrients and other essential components to function properly. It would lead to a loss of energy and make it difficult to move and work as usual. However, weakness could be caused by many health issues, so make sure to consult your doctor and get a precise diagnosis. If it is followed by other symptoms mentioned above or below, then these might indicate the presence of atrial fibrillation. [2]
