An irregular heartbeat commonly referred to as palpitations is one of the most common signs of atrial fibrillation.
Signs and symptoms of Afib usually result from poor blood supply to the heart or the rest of the body. [Source: Johns Hopkins Medicine]
Some people with atrial fibrillation may experience chest pain or discomfort due to a reduced blood supply to the heart.
Atrial fibrillation causes a decrease in blood flow to the brain, which might lead to lightheadedness or dizziness.
Atrial fibrillation results in improper heart pumping and an inability to efficiently pump oxygenated blood to the rest of your body, which can lead to weakness.
Atrial fibrillation causes blood to accumulate in the upper chambers of your heart, which might lead to shortness of breath, especially during physical activity.
Atrial fibrillation might develop insomnia or difficulty sleeping because of the symptoms such as palpitations or shortness of breath.
A person with atrial fibrillation might sometimes faint due to insufficient blood supply to the brain. (Source: Johns Hopkins Medicine)
