Brugada syndrome, also known as sudden unexpected nocturnal death syndrome, is a rare and hereditary heart condition that affects the electrical system of the heart. It is characterized by abnormal heart rhythms and an increased risk of sudden cardiac arrest. Some synonyms for the term "Brugada syndrome" include ventricular fibrillation, ventricular tachycardia, arrhythmogenic right ventricular dysplasia, and sudden arrhythmic death syndrome. While there is currently no cure for Brugada syndrome, it can be managed with the use of implantable cardioverter-defibrillator devices or medications. It is important for individuals with a family history of Brugada syndrome or who have experienced cardiac symptoms to seek medical attention immediately.
