title: [Electrocardiographic predictors of in-hospital outcomes of acute coronary syndrome].
abstract: OBJECTIVE
  To estimate the time course of changes in basic electrocardiographic (ECG) parameters in patients with acute coronary syndrome (ACS) as possible predictors of in-hospital outcomes.
  
  
  METHODS
  The data of 277 patients with acute coronary syndrome (ACS) were used; QT-interval duration was studied by means of an EC12C-01 cardioanalyzer; ST-segment deviation (sigmaST), elevation (sigmaST-E), and depression (sigmaST-D) sums, and corrected QT-interval dispersion (DQTc) were calculated.
  
  
  RESULTS
  There were highly significant differences of sigmaST in all the patients groups at admission and differences of DQTc in ACS patients with and without ST-segment elevation. The survival rates were significantly different depending on the value of ECG parameters, such as sigmaST, sigmaST-D, and DQTc.
  
  
  CONCLUSIONS
  The cardioanalyzer can automatically improve the estimation of in-hospital ECG changes and to determine predictors of an ACS outcome.
