•!Recently discovered

–!First case in 1989

–!Officially recognized in

1992 by Brugada brothers

•!Genetic disorder

•!Causes arrhythmia through

ventricular fibrillation

•!Around 60% of sufferers have family history of Brugada syndrome

•!Autosomal dominant

•!Predominance in males

•!Several mutations affecting gene SCN5A which codes for cardiac sodium channels

•!Polymorphic ventricular tachycardia-ventricular fibrillation

•!Syncopal attacks (fainting)

•!Cardiac arrest or sudden death

•!Genetic defect in a cardiac sodium channel

•!Results in altered channel function where there is a temperature dependent loss of sodium current

•!Creates a variety of refractory period lengths which can cause arrhythmias

•!Anti-arrhythmic drugs do not protect against sudden death

•!Only current treatment is an implantable cardioverter-defibrillator which recognizes and treats

ventricular arrhythmias

•!Also known as ‘Sudden Unexpected Death Syndrome’ (SUDS)
