Objective To study the clinical features of cardiac arrest patients and the influence factors of effective resuscitation. Methods The clinical data of 76 patients in our hospital who underwent cardiac arrest and resuscitation were analyzed retrospectively. Results The effective resuscitation were observed in forty-seven patients (47/76, 61.8%), 28 patients completely survived(28/76,36.8%), and the total death rate was 63.2%. The successful rate of resuscitation was positive relation to the starting time of resuscitation, the way of cardiac arrest, and the structure and function of heart, but was negative relation to the times of cardioversion. The successful rate of resuscitation had indefinite relation with the patients age and gender. Conclusion The immediate cardioversion was the key factor of successful resuscitation.The successful resuscitation was dependent on the continuous and effective cardio-press. Basical cardio-disease was the major factor affecting prognosis.
