Brugada Syndrome

BrS is a condition that affects the electrical activity of your heart. It can cause an abnormal heart rhythm, known as an arrhythmia. Arrhythmias can occur during fever, rest or sleep. This abnormal heart rhythm can lead to a sudden fainting spell or a seizure. If the arrhythmia continues for a long period of time, it can cause sudden death.

What are the symptoms of BrS?

  • Fainting, including dizziness, racing heart (palpitations) and blurred vision
  • Seizures
  • Sudden death

What causes BrS?

BrS can be inherited or acquired. Inherited BrS means that there is a change in your DNA that causes BrS. Acquired BrS can occur when you take certain medications. The list of medications that are associated with acquired BrS can be found on www.brugadadrugs.org.

How is BrS diagnosed?

  • Electrocardiogram (EKG or ECG) with medication, a test that measures the electrical activity of your heart
  • EKG with medication, a test that measures the electrical activity of your heart after taking a medication that can unmask BrS
  • Genetic testing, a blood test to find a change in your DNA that causes BrS

How is BrS treated?

Treatment of BrS involves treating the arrhythmia, or abnormal heart rhythm. This treatment includes medications or an implantable device. It is important to discuss with your physician what medications should be avoided when you have BrS, to prevent triggering an arrhythmia.
