title: Differences of Ventricular Late Potential between Acute STEMI and NSTEMI Patients.
abstract: OBJECTIVE
  To discuss the positive rate of ventricular late potential (VLP) between patients with acute ST-segment elevation myocardial infarction (STEMI) and patients with acute non NSTEMI.
  
  
  METHODS
  One hundred and sixty-three cases of acute myocardial infarction (90 patients with STEMI and 73 with NSTEMI), admitted to the First Hospital of China Medical University between June 2011 and August 2011, underwent VLP examination.
  
  
  RESULTS
  The VLP positive rate of the STEMI group was 54.4%, while that of the NSTEMI group was 38.4%, and the differences have statistical meaning (χ2 = 4.186, p < 0.05). The occurrence rate of ventricular arrhythmia in VLP positive patients was 11.7%, while in VLP negative patients it was 3.5% (χ2 = 4.005, p < 0.05).
  
  
  CONCLUSIONS
  The VLP positive rate of the STEMI group is higher than that of the NSTEMI group.
