Symptoms
Symptoms of
atrial fibrillation include:
- Heart
palpitations.
- Irregular pulse.
- Shortness of
breath, especially during physical activity or emotional
stress.
- Weakness, fatigue.
- Dizziness,
confusion.
- Lightheadedness or fainting (syncope).
- Chest pain (angina).
Atrial fibrillation is often discovered during routine medical
checkups, because many people do not have symptoms. Others may notice an
irregular pulse but do not have other symptoms.
Mild symptoms may develop immediately. More serious problems may
develop after the start of atrial fibrillation and over the course of several
days. Therefore, it is important to identify and treat atrial fibrillation as
soon as possible to avoid serious problems.
Serious complications such as a
stroke,
heart attack, or
heart failure may occur before atrial fibrillation is
discovered.
