Context There are numerous potential benefits to better understanding the prognosis of victims of initially non-shockable cardiac arrests including changes to future resuscitation care guidelines. Objective To evaluate whether out-of-hospital cardiac arrest outcomes for patients whose initial arrest rhythm is non-shockable improve or worsen with subsequent conversion to shockable rhythms. Design, Setting, and Patients This study is a cohort design secondary analysis of the prospectively-collected Cardiac Arrest Epidemiologic Registry (Epistry) organized by the Resuscitation Outcomes Consortium (ROC) of all out-of-hospital cardiac arrests at eight North American sites (6 US and 2 Canadian) between December 1, 2005, to May 31, 2007, followed through hospital discharge. The investigational cohort is identified as all EMS-treated adult (18 and older) cardiac arrest patients who presented in non-shockable rhythms (Pulseless Electrical Activity, Asystole, or Automated External Defibrillator
