Brugada syndrome is a rare inherited cardiovascular disorder characterized by disturbances affecting the electrical system of the heart. The main symptom is irregular heartbeats and, without treatment, may potentially result in sudden death. In some cases, no symptoms may precede sudden death. Brugada Syndrome typically begins onset in adulthood and follows autosomal dominant inheritance. The prevalence rate of the disease is currently unknown due to its recent identification.
The normal heart has four chambers. The two upper chambers are known as the atria and the two lower chambers are known as the ventricles. Electrical impulses cause the heart to beat. In individuals with Brugada syndrome, the electrical impulses between the ventricles become uncoordinated (ventricular fibrillation) resulting in decreased blood flow. Decreased blood flow to the brain and heart may result in fainting or sudden death.
Brugada syndrome is named by the Spanish cardiologists Pedro Brugada and Josep Brugada who reported it as a distinct clinical syndrome in 1992.
