title: An unusual case of syncope in a young female with incidental long QTc interval.
abstract: Syncope is a common presentation to emergency departments. Arrhythmias account for 14% of those presentations [1], which requires careful assessment due to the potential for sudden cardiac death (SCD). QTc prolongation either due to congenital channelopathy or acquired aetiology can lead to polymorphic ventricular tachycardia and SCD, and should be excluded on electrocardiography. On the other hand, detailed history and thorough clinical examination are the most important tools in reaching the diagnosis, even in the presence of QTC prolongation.
