Medical Definition of Brugada syndrome

: an inherited life-threatening cardiac disorder of abnormal heart rhythm that may be marked by episodes of fainting or that may be asymptomatic until ventricular tachycardia results in ventricular fibrillation leading to cardiac arrest or sudden cardiac death In patients with Brugada syndrome … abnormal electrical signals sporadically stop their hearts from pumping properly.— Duncan Graham-Rowe, New Scientist, 3 Apr. 2004

Note: Brugada syndrome is typically diagnosed by the presence of an elevated ST segment and partial to complete bundle branch block of the right ventricle. It is inherited as an autosomal dominant trait requiring that only one parent pass on a copy of the defective gene on a chromosome other than a sex chromosome.
