Brugada syndrome

Brugada syndrome (pronounced: broo-GAH-dah sin-drome) is a potentially life-threatening heart rhythm disorder that is sometimes inherited. People with Brugada syndrome have an increased risk of abnormal heart rhythms from the lower chambers of the heart (ventricular arrhythmias).

Etymology

The syndrome is named after the Spanish cardiologists Pedro Brugada and Josep Brugada who described the syndrome in 1992.

Symptoms

Most people with Brugada syndrome don't know they have it because the condition often doesn't cause noticeable symptoms. For some people, Brugada syndrome can cause heart palpitations, fainting, or sudden death due to a ventricular fibrillation.

Causes

Brugada syndrome is often inherited, but it may also result from a change in a gene or genes. This condition is often passed down through families (inherited) as an autosomal dominant trait. The syndrome is associated with a mutation in the SCN5A gene and other genes.

Diagnosis

Brugada syndrome is diagnosed based on an electrocardiogram (ECG) test. The ECG may show a pattern called a type 1 Brugada ECG pattern. Other tests may include a genetic test to look for mutations in the SCN5A gene or other genes.

Treatment

There's no cure for Brugada syndrome. Treatment might involve medications, a implantable cardioverter-defibrillator (ICD), or sometimes surgery.
