Brugada Syndrome (Heart): Who Would Bridge the Gap?

Brugada Syndrome is a rare but potentially life-threatening inherited heart condition that affects the electrical system of the heart. It can cause dangerous arrhythmias (irregular heartbeats) and sudden cardiac death, often in otherwise healthy young adults — sometimes with no prior warning.

What Is Brugada Syndrome?

Brugada Syndrome is caused primarily by mutations in the SCN5A gene, which encodes a sodium channel protein critical for normal heart rhythm. When this channel malfunctions, it can trigger ventricular fibrillation — a chaotic, life-threatening heart rhythm. The condition is more common in men and in people of Asian descent, and symptoms often appear during sleep or at rest.

Signs and Risk Factors

• Unexplained fainting (syncope), especially during rest or sleep

• Family history of sudden cardiac death, especially in young relatives

• Characteristic “Brugada pattern” on an ECG

• Fever can unmask or worsen the condition

• Certain medications can trigger episodes

The Diagnostic Gap

Brugada Syndrome is frequently underdiagnosed because its ECG pattern can be intermittent and symptoms are non-specific. Many individuals are only diagnosed after a cardiac event — or after a family member suffers sudden cardiac death. Genetic testing can identify SCN5A mutations in at-risk individuals and their family members, enabling proactive monitoring and management before a crisis occurs.

Management

There is no cure for Brugada Syndrome, but it can be managed. An implantable cardioverter-defibrillator (ICD) is the most effective treatment for high-risk individuals. Avoiding triggers — fever, certain drugs, and excessive alcohol — is also critical. Family members of affected individuals should be screened.
