title: [Thoracic pain and early repolarization syndrome at the cardiologic emergency unit].
abstract: OBJECTIVE
  To analyze the clinical and electrocardiographic characteristics of early repolarization syndrome (EP) in patients with thoracic pain.
  
  
  METHODS
  Patients with thoracic pain and early repolarization were studied. EP was diagnosed on the basis of the presence of two or more criteria: ST elevation; upward concavity; notch or slur on QRS; assymetrical T waves of large amplitude; U waves.
  
  
  RESULTS
  Of 350 patients treated in the emergency department, 17 were studied. Sixteen were men, mean age 43.9 years. Four were black. The thoracic pain was atypical in 15. All the patients had ST elevation with upward concavity, most frequently in leads V2. Tall, peaked, positive waves were found in nine patients and U waves were present in 14.
  
  
  CONCLUSIONS
  The electrocardiographic characteristics of ST elevation with upward concavity most frequently observed in precordial leads in patients with atypical precordial pain are important to establish a differential diagnosis, to be confirmed by previous electrocardiogram and cardiac enzymes.
