Brugada Syndrome

What is Brugada Syndrome?

Brugada syndrome is a rare, potentially life-threatening delay in the signal in the front of the heart. It’s more common in adults men and Asians. Most patients with Brugada syndrome have no symptoms, so the condition isn’t diagnosed.

Signs of Brugada syndrome include:

  • Fainting
  • Dizziness
  • Palpitations or irregular heartbeat
  • Laboured breathing, especially at night

The heart’s electrical system requires electrical signals to go through specialized electrical tissue and the heart muscle (myocardium). The electrical tissues and the myocardium conduct electricity due to special molecules called ion channels. If you have Brugada syndrome, there is a defect in one of the ion channels.

Patients with Brugada are at risk of developing an abnormal heart rhythm, which can cause fainting, seizures or sudden death (usually when a person is resting or asleep).

An electrocardiogram (ECG) test may recognize an abnormality called a type 1 Brugada ECG pattern. Your doctor may also recommend an electrophysiology (EP) test or genetic testing.

Brugada syndrome may be inherited, due to an structural heart abnormality, electrolyte imbalances, cocaine use or certain prescription medications.

Brugada Syndrome Treatment

If you’re diagnosed with Brugada syndrome, your physician may prescribe:

  • Medications to prevent the heart from going into potentially dangerous rhythm
  • An implantable cardioverter-defibrillator (ICD) that continuously monitors heart rhythm and delivers electrical shocks when needed

If you experience arrhythmia (an irregular heartbeat) or palpitations or an irregular heartbeat, see your primary care provider as soon as possible. If you faint and believe it could be related to a heart condition, seek emergency medical attention.
