Brugada syndrome is a genetic heart disease. It is characterized by the alteration in the genes that are in charge of the formation of the cardiac proteins that regulate the passage of the ions of the cellular membrane. The electrocardiogram is the main test to diagnose this disease. An echocardiogram is also necessary to see if there are abnormalities in the structure of the heart. There is also a genetic test that can identify this genetic alteration and confirm the disease.
