Successful resuscitation after out-of-hospital cardiac arrest.

A 66-year-old woman presented to the emergency department after a witnessed cardiac arrest, having had compression-only cardiopulmonary resuscitation initiated by her son on the backseat of his car. She was resuscitated in the emergency department for 1 hour before the return of spontaneous circulation. She then underwent primary percutaneous coronary intervention and therapeutic hypothermia. She was discharged without significant neurological deficit. This case illustrates better survival and neurological outcome can be achieved by prompt implementation of a 'chain of survival' interventions and therapeutic hypothermia.
