Symptoms

Many people with Brugada syndrome don't know they have the condition. Brugada syndrome often doesn't cause any noticeable symptoms.

Signs and symptoms that may be associated with Brugada syndrome include:

• Dizziness
• Fainting
• Gasping, labored breathing, particularly at night
• Irregular heartbeats or palpitations
• Extremely fast and chaotic heartbeat
• Seizures

A major sign of Brugada syndrome is an abnormal result on an electrocardiogram (ECG), a test that measures the electrical activity of the heart.

When to see a doctor

Brugada syndrome signs and symptoms are similar to some other heart rhythm problems. It's important that you see your doctor to find out if Brugada syndrome or another heart rhythm problem is causing your symptoms.

If you faint and you think it may be because of a heart condition, seek emergency medical attention.

If your parent, sibling or child has been diagnosed with Brugada syndrome, you may want to ask your doctor if you should have testing to see if you're at risk of Brugada syndrome.
