The evaluation may begin with consideration of the most common causes. However, it is important to exclude the rare causes, including cardiac arrhythmias that may lead to sudden death in young patients. Brugada syndrome and catecholaminergic polymorphic ventricular tachycardia are some of the rare causes of primary electrical disorders of the heart. High suspicion of these disorders in the evaluation, and appropriate referral to a cardiologist may prevent sudden deaths in these patients. Here, we report 2 children with arrhythmogenic causes of syncope. © 2014 Lippincott Williams & Wilkins, Inc.
