title: Atypical Presentation of Right Ventricular Outflow Tract Ventricular Tachycardia.
abstract: BACKGROUND
  Ventricular tachycardia (VT) in the pediatric population is rare, has a wide differential diagnosis, and can present in numerous ways. In the absence of underlying heart disease, VT is considered idiopathic and is associated with an excellent prognosis. Right ventricular outflow tract ventricular tachycardia (RVOT-VT) represents the most common form of idiopathic VT. The differential diagnosis, mechanism, presentation, management, and prognosis of RVOT-VT in the pediatric population will be discussed.
  
  
  METHODS
  We report a case of RVOT-VT that was incidentally discovered in an 11-year-old girl during an emergency department workup for severe headache. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: It is essential for emergency physicians to have an approach to pediatric VT and appreciate the wide range of potential presentations. Differentiating idiopathic VT, such as RVOT-VT, from more malignant forms of VT can be challenging and requires expert consultation for further diagnostic workup and management.
