title: Atypical presentation of "takotsubo cardiomyopathy" without ST segment elevation: a case report.
abstract: BACKGROUND
  "Takotsubo cardiomyopathy" is characterized by transient LV dysfunction and mimicking acute myocardial infarction.
  
  
  METHODS
  We reported a case with atypical presentation of "takotsubo cardiomyopathy" without ST segment elevation, but with severe transient left ventricular dysfunction.
  
  
  CONCLUSIONS
  Diagnosis of "takotsubo cardiomyopathy" should be based on typical left ventricular dysfunction without coronary artery disease.
