What is Brugada syndrome?

Brugada syndrome is a condition that causes an abnormal heart rhythm in the heart's lower chambers (ventricles). This irregular heartbeat can cause fainting (syncope) and lead to sudden cardiac death (SCD).

Brugada syndrome is a rare disease that is inherited (genetic) from at least one parent. It was first discovered in 1992. A lot has been learned about the condition since then, but there are still many unanswered questions. Researchers continue to study Brugada syndrome and test new treatments.

What causes Brugada syndrome?

Brugada syndrome is often caused by a genetic mutation. The defect changes the way the heart's ion channels work (a problem called a channelopathy).

Who is at risk of having Brugada syndrome?

Brugada syndrome is more common in males than females. In fact, men are 8 to 10 times more likely than women to have the condition. All patients with a family history of SCD or Brugada syndrome should be screened for the disease.

Do You Need to be Screened for Brugada Syndrome?

Brugada Syndrome is a medical condition that can be passed on from generation to generation. It is important for you to be screened for this condition if you have a first-degree relative with Brugada Syndrome. First-degree relatives are your parents, siblings and children.

The first step is to tell your doctor that you have a family history of this condition. He or she may want to do diagnostic tests to check your heart. If these tests are positive, you should be seen by a cardiologist who is familiar with this condition.
