Establishment of coronary care units (CCU) cause decreasing in
   hospital’s mortality after cardiac arrest, because life threatening arrhythmias
   could be reversible by effective measures. The aim of this study was
   ascertainment of  short term(in hospital) prognosis of patients who admitted
   in Hamadan’s Ekbatan Hospital’s CCU and experienced cardio pulmonary
   resuscitation (CPR) after cardiac arrest.

          This study was descriptive, cross-sectional and prospective and included
   101 patients who admitted in CCU since 1997 to 1998 and experienced at
   least one CPR.

          In present study the most common mechanism of cardiac arrest in
   successful CPR was ventricular fibrillation and in unsuccessful CPR was
   asystol and bradycardia. 20. 8% of patients who experienced cardiac arrest
   had successful CPR and discharged from hospital.

          20.8% of patients had successful CPR and hospital discharge which in
   comparison to the same studies is acceptable and indicate good quality of
   aforementioned CCU.
