Survival in out-of-hospital cardiac arrests with initial asystole or pulseless electrical activity and subsequent shockable rhythms

Outcome of out-of-hospital postcountershock asystole and pulseless electrical activity versus primary asystole and pulseless electrical activity.

OBJECTIVE In the prehospital setting, countershock terminates ventricular fibrillation (VF) in about 80% of cases. However, countershock is most commonly followed by asystole or pulseless electrical activity (PEA). The consequences of such a countershock outcome have not been well studied. The purpose of this investigation was to compare the outcome of prehospital VF victims shocked into asysto...

Outcomes following out-of-hospital cardiac arrest with an initial cardiac rhythm of asystole or pulseless electrical activity in Victoria, Australia.

BACKGROUND While internationally reported survival from out-of-hospital cardiac arrest (OHCA) is improving, much of the increase is being observed in patients presenting to emergency medical services (EMS) in shockable rhythms. The purpose of this study was to assess survival and 12-month functional recovery in patients presenting to EMS in asystole or pulseless electrical activity (PEA). MET...

Subsequent Shockable Rhythm During Out‐of‐Hospital Cardiac Arrest in Children With Initial Non‐Shockable Rhythms: A Nationwide Population‐Based Observational Study

BACKGROUND The effect of a subsequent treated shockable rhythm during cardiopulmonary resuscitation on the outcome of children who suffer out-of-hospital cardiac arrest with initial nonshockable rhythm is unclear. We hypothesized that subsequent treated shockable rhythm in children with out-of-hospital cardiac arrest would improve survival with favorable neurological outcomes (Cerebral Performa...

Application of ultrasound in pulseless electrical activity (PEA) cardiac arrest

Who survives from out-of-hospital pulseless electrical activity?

AIM OF THE STUDY To study factors associated with short-term and long-term survival after out-of-hospital cardiac arrest presenting with pulseless electrical activity (PEA). MATERIALS AND METHODS This was a retrospective observational study. All out-of-hospital cardiac arrests in Helsinki, Finland during 1 January 1997-31 December 2005 were prospectively registered in the cardiac arrest datab...
