      Electrocardiographic findings in patients with acute coronary syndrome presenting with out-of-hospital cardiac arrest.
      The authors reported better outcomes in patients with acute coronary syndrome who presented with out-of-hospital cardiac arrest (OHCA) if initial electrocardiogram (ECG) showed ST-segment elevation, worse outcome if left bundle branch block was observed, and no influence on outcome if right bundle branch block or ST-segment denivelation occurred.
