title: [Differential diagnosis of early repolarization syndrome in patients with ST-segment elevation: report of 5 cases].
abstract: OBJECTIVE
  To explore the differential diagnosis of early repolarization syndrome (ERS) in patients with ST-segment elevation and its clinical significance.
  
  
  METHODS
  Five patients with ESR were clinically observed and followed up after discharge from hospital.
  
  
  RESULTS
  All the patients complained of chest distress or chest pain, accompanied by ST-segment elevation in the precordial electrocardiogram leads.
  
  
  CONCLUSIONS
  ESR is often misdiagnosed as acute myocardial infarction, acute coronary syndrome, Brugada syndrome or other diseases that may involve elevated ST-segment, and careful examination of the ECGs, echocardiogram, troponin I and the patients' history of heart diseases may help differentiate ESR from these diseases.
