Introduction: cardiovascular diseases are the leading cause of death in Uruguay. Is estimated that half of these deaths presents as cardiac arrest within the first hour of onset of symptoms. Methods: this is a retrospective descriptive-analytic study of nontraumatic adult out of hospital cardiac arrest (OHCA) between 2007 and 2011 in Montevideo. We performed chi-square test, t test and logistic regression to analyze the association of variables. Results: 692 patients were treated by non-traumatic OHCA. The average age was 71.5 y.o., 57.2% male. The median time of the call-arrival reception was 9 minutes. The rhythms on arrival were: asystole 59.3%, ventricular fibrillation 22.6%, pulseless electrical activity 16.8% and pulseless ventricular tachycardia 1.01%. The survival to hospital admission (SHA) was 21.2%. In univariate analysis in reference to the SHA statistical significance was observed in the following variables: public place (p = 0.0004), ventricular fibrillation (p <0.0001), PVT (p = 0.01), asystole (p <0.0001) and age (p = 0.004). When considered together shockable rhythms were associated with greater SHA (p <0.0001). In multivariate analysis referred to to the SHA statistical significance was observed in the variable shockable rhythms (p <0.0001). Conclusion: Times of emergency response were acceptable.Survival to hospital admission is similar to that reported in international studies. The OHCA shockable rhythms, a public place  where the event occurs and lower age were associated with more survival to hospital admission
