Brugada syndrome is a genetic disease in the heart's electrical system with abnormal electrocardiogram (ECG) finding and an increased risk of sudden cardiac death from life-threatening arrhythmias. It is diagnosed by specific abnormalities on the ECG.

At the cellular level, tiny pores, called ion channels, on each of these cells direct the electrical activity of the heart. In the Brugada syndrome, a defect in these sodium channels causes episodes of abnormal electrical function leading to potentially fatal arrhythmias.

​Most of Brugada patient remained asymptomatic. Symptoms include palpitations, sudden loss of consciousness or sudden cardiac death.

​There is no prevention. Screening of immediate family members will help to identify individuals at risks and lifestyle modification advice can be given.

Diagnosis typically starts with a physical examination by a doctor, assessing your medical history and conducting routine tests. Other tests recommended may include:

• Electrocardiogram (ECG)
• Flecanide challenge test

There is no specific treatment for Brugada Syndrome.

Lifestyle modifications include avoidance of drugs which may potentially result in arrhythmias, proper treatment and control of fever, avoidance of excessive alcohol or large meals, maintaining good hydration and electrolyte balance.
