AB ESSENTIALS  OF  DIAGNOSISSudden  cardiac  death  is  near  instantaneous  death  due  to  underlying  cardiac  cause  and  may  include  arrhythmic  and  non-arrhythmic  causes.Conventional  definitions  use  death  certificates,  emergency  medical  systems  records,  or  epidemiologic  criteria  to  define  sudden  cardiac  death,  but  these  methods  do  not  reliably  exclude  non-arrhythmic  causes  of  sudden  death.More  recent  studies  use  postmortem  investigation  to  more  accurately  define  sudden  arrhythmic  death.Sudden  cardiac  death  is  primarily  intended  to  specify  sudden  deaths  due  to  arrhythmic  cause,  that  is,  sudden  arrhythmic  death  that  is  potentially  rescuable  with  a  defibrillator.Common  underlying  etiologies  and  risk  factors  for  sudden  arrhythmic  death  include  coronary  artery  disease,  nonischemic  cardiomyopathy,  and  other  structural  heart  diseases  such  as  left  ventricular  hypertrophy;  primary  electrical  diseases  are  a  rare  cause.Many  noncardiac  causes  may  underlie  sudden  cardiac  arrest  and  sudden  deaths,  such  as  neurologic  catastrophe,  hemorrhage,  occult  overdose,  and  pulmonary  embolism.
