| Summary: | <p><strong>Introduction:</strong></p><p>Bradyarrhythmias are serious heart diseases that cause severe hemodynamic disorders. Bringing the patient to normal cardiac output may imply that a pacemaker be implanted.</p><p><strong>Objective:</strong></p><p>To describe some clinical and epidemiological aspects of patients who received the technique of implanting a pacemaker.</p><p><strong>Methods:</strong></p><p>A descriptive and cross-sectional study was carried out with 36 patients who needed a temporary pacemaker, admitted to the intensive care unit of Orlando Pantoja Tamayo General Teaching Hospital in Contramaestrem, in the period from October 2015 to May 2019. The variables used were age group and sex, causes of arrhythmias, and personal pathological history, most used medications prior to admission, time of usage of the temporary pacemaker, and the need for permanent implantation.</p><p><strong>Results:</strong></p><p>The male sex and ages 80 and older predominated, the most frequent atrioventricular conduction disorder was the third-degree atrioventricular block. The average time of temporary pacemaker usage was between two and six days.</p><p><strong>Conclusions:</strong></p><p>Early implantation in this municipal institution significantly improved patient survival.</p><strong>Keywords:</strong> conduction disorders; bradyarrhythmias; temporary pacemaker
