title: Ventricular Fibrillation in a General Population　- A National Database Study.
abstract: Ventricular fibrillation (VF) is a life-threatening disease that can be remedied by prompt defibrillation. However, data regarding such risk in a general population remain limited. This general population study was to explore the epidemiological profile of VF.
  
  
  
  We investigated patients with VF younger than 60 years (average population, 19,725,031) using a national database spanning the period 2000-2010. We identified 3,971 (68.4% male) patients with VF (crude incidence rate: 1.83/100,000). Incidence rates were low in patients younger than 10 years and increased steadily after adolescence. Comorbidities were noted in 2,766 (69.7%) patients, with 2,431 (61%) having cardiac diseases. Over half of the adolescent and young adult patients did not have comorbidities. Among the 838 deaths (mortality rate 21.1%), approximately half (381/838, 45.5%) occurred after arrival at emergency services (ES). The proportion of deaths after arrival at ES relative to total deaths increased sharply to a peak in the 15-19-years age group and thereafter remained stationary.
  
  
  
  VF patients, with a male dominance, increased after adolescence and were likely to die at presentation to ES. Approximately half of young adults, with high mortality, did not have comorbidities, suggesting underdiagnosis of underlying primary electrical diseases and the need for implementing automated external defibrillator programs.
