The abnormal heart rhythms seen in those with Brugada syndrome are typically dangerous arrhythmias such as ventricular fibrillation or polymorphic ventricular tachycardia, but those with BrS are also more likely to experience rapid heart rates due to less dangerous arrhythmias such as AV nodal re-entrant tachycardia[1] and abnormally slow heart rhythms such as sinus node dysfunction.[2] There are several mechanisms by which the genetic mutations causing this condition might produce these arrhythmias.[3]
