Brugada syndrome is a rare, often inherited condition that causes irregular beats in the bottom chambers of the heart.
What is Brugada syndrome?
Brugada syndrome (BrS) is a heart rhythm disorder that causes abnormal beats in the bottom chambers of the heart (ventricles). If left undiagnosed, Brugada syndrome can cause fainting, irregular heartbeats and sudden death.
What are the symptoms of Brugada syndrome?
Many people with Brugada syndrome do not show symptoms. However, some may experience:
- Fainting
- Blackouts
- Irregular heartbeat
- Extremely fast and chaotic heartbeat
- Unexplained nighttime urination
Symptoms typically first appear around 30-40 years of age and are more common in men than women.
How is Brugada syndrome diagnosed?
Brugada syndrome can be difficult to diagnose. Your doctor will review your medical history and have you do an electrocardiogram (ECG). You may also be asked to do a genetic test as Brugada syndrome is usually inherited.
What treatment is available for Brugada syndrome?
If you are at risk of developing a dangerously fast heartbeat, your doctor may recommend that you have an implantable cardioverter defibrillator (ICD) implanted.
You can also reduce your risk of developing a fast heartbeat by avoiding things that can trigger it. These include a high fever, drinking too much alcohol, dehydration and avoiding medication that may trigger the condition. Ask your doctor about which medications to avoid.
