title: A teenage girl with extreme tachypnea.
abstract: Dyspnea and tachypnea are common presenting complaints in an emergency department. Respiratory and cardiac causes are the most common etiology. Functional respiratory disorders should be considered in patients with atypical presentation to avoid extensive investigations. We describe an adolescent who presented to our emergency department with extreme tachypnea.
