Brugada (brew-GAH-dah) syndrome is a potentially life-threatening heart rhythm disorder that is sometimes inherited. People with Brugada syndrome have an increased risk of abnormal heart rhythms from the lower chambers of the heart (ventricular arrhythmias).
Many people who have Brugada syndrome don't have any symptoms, and so they're unaware of their condition. A telltale abnormality — called a type 1 Brugada ECG pattern — is detected by an electrocardiogram (ECG) test. Brugada syndrome is much more common in men.
Brugada syndrome is treatable with preventive measures such as avoiding aggravating medications, reducing fever and, when necessary, using a medical device called an implantable cardioverter-defibrillator (ICD).
