Common symptoms of atrial fibrillation include heart palpitations, a pulse that is faster than normal, and tightness or discomfort in the chest. When atrial fibrillation reduces the amount of blood the heart pumps, the body may not get enough oxygen. This can cause additional symptoms like shortness of breath, dizziness, and feeling tired. Atrial fibrillation can also lead to serious complications such as a heart attack or stroke, so it's important to know how signs of these conditions differ from the symptoms of atrial fibrillation.
