Brugada Syndrome is a cause of ventricular tachyarrhythmias that may lead to syncope, cardiac arrest, or sudden cardiac death. It is more common in men and those of Asian ethnicity. The cause is due to an inherited channelopthay (can occur sporadically), most commonly involving the sodium channel. The classic EKG finding is ST elevation with a “saddle back” appearance in V1-V3 often coexistent with an incomplete RBBB. The EKG findings are transient and variable and may not be seen during ED evaluation.
