Signs and Symptoms

Fainting and Cardiac Arrest

Syncope (fainting) and cardiac arrest are the most common signs and symptoms of Brugada syndrome. However, sometimes there are no symptoms.

Electrocardiogram May Provide Diagnostic Clue

An EKG may provide a diagnostic clue to this diagnosis but is not sufficient to make the diagnosis of Brugada syndrome and clinical correlation is required. It is possible to have a Brugada pattern on your EKG and not have Brugada syndrome. This pattern can also be caused by a structural abnormality in your heart, abnormal electrolyte levels or side effects of certain medications.
