AB  - BACKGROUND: Recent studies found that early repolarization (ER) is significantly 
      more common in survivors of aborted sudden cardiac death. We hypothesized that ER 
      might be more common in patients with ST elevation myocardial infarction (STEMI) 
      who have complications of atrial and ventricular arrhythmias. METHODS: This study 
      included 266 patients with acute STEMI undergoing primary percutaneous coronary 
      intervention. Twelve-lead electrocardiograms were analyzed for ER, defined as 
      J-point elevation >/= 0.1 mV and "notching" and "slurring" of the terminal part of 
      the QRS complex in at least 2 lateral or inferior leads. Acute and late atrial 
      and ventricular arrhythmic events were evaluated. RESULTS: The ER pattern was 
      observed in 76 patients (28.6%). Atrial arrhythmia [21/76 (27.6%) vs. 22/190 
      (11.6%), p=0.001] and ventricular arrhythmia [16/76 (21.1%) vs. 16/190 (8.4%), 
      p=0.004] were more frequently complicated in patients with ER than those without 
      during hospitalization. ER was a significant independent predictor of developing 
      atrial (HR=2.682, 95% CI=1.355-5.310, p=0.005) and ventricular arrhythmia 
      (HR=2.936, 95% CI=1.360-6.335, p=0.006). Three patients with ER and ventricular 
      fibrillation expired during hospitalization [3.9% (3/76) vs. 0% (0/190), 
      p=0.023]. However, the presence of ER did not affect the late recurrence of 
      atrial and ventricular arrhythmia. CONCLUSIONS: The ER pattern is commonly 
      observed in patients with STEMI and associated with atrial and ventricular 
      tachyarrhythmia during acute setting.
