ECGs in the ED.

摘要

A 6-year-old boy presents to the emergency department for evaluation of chest pain. The pain has occurred in the past and is always described as sharp, parasternal, and exacerbated by deep inspiration. The episodes usually recover spontaneously within 5 or 10 minutes. The pain today was more severe and lasted longer, which prompted the parents to bring the child to the emergency department. The patient has been in his usual state of health. He denies palpitations, shortness of breath, dizziness, or syncope. There is no history of trauma to the chest. There has been no recent fever, upper respiratory tract symptoms, headache, or rash. The past medical history is noncontributory.
