Prognosis of early versus late ventricular fibrillation complicating acute myocardial infarction

Abstract Earlier studies have suggested that patients exhibiting late (> 24 h) ventricular fibrillation during acute myocardial infarction had a poorer outcome in comparison to myocardial infarction patients with early ( n = 107) were excluded from analysis. Patients with late ventricular fibrillation ( n = 109; 41%) were older and had a more complicated hospital course than patients with early ventricular fibrillation ( n = 155; 59%). In-hospital and 1-year post-discharge mortality were significantly higher in patients with late ventricular fibrillation (63% and 17%) as compared to patients with early ventricular fibrillation (26% and 4%, respectively; P
