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.
