title: [The changes of electrocardiogram and serum cardiac troponin I at the early stage of crush injury in rats].
abstract: OBJECTIVE
  To observe the changes of electrocardiogram and serum cardiac troponin I at the early stage of severe crush injury in rats.
  
  
  METHODS
  Crush injury was produced in Sprague-Dawley rats. The changes of electrocardiogram were recorded with the standard II, the serum levels of cardiac troponin I were studied by automated chemiluminescence assay.
  
  
  RESULTS
  The ST segment elevated considerably after crush injury and lasted 24 h, the levels of serum cTnI were much higher than those of the control groupes after 6 h of injury.
  
  
  CONCLUSIONS
  Cardiomyocyte injury was induced in the early phase of crush injury.
