The main aim when treating people with Brugada syndrome is to reduce the risk of sudden death due to serious abnormal heart rhythms such as ventricular fibrillation or polymorphic ventricular tachycardia.[26] While some with this condition are at high risk of serious heart rhythm disturbances, others are at much lower risk, meaning that some may require more intensive treatment than others.[2] In addition to treating the person who has Brugada syndrome, it is often important to investigate members of their immediate family to see if they too carry the condition.[8]
