Sudden cardiac death (SCD) is unexpected natural death due to cardiac causes, with abrupt loss of consciousness within 1 h of the onset of acute symptoms, with or without pre-existing heart disease. It is very hard to assess the exact incidence of SCD because of variability in the definition of the concept of “sudden” [1,2]. We are not discussing death occurring 1 h after syncope in a healthy subject, but the definition is not completely clear in a cardiopathic patient with ventricular fibrillation as the end-stage event in a worsened clinical status.
