Introduction. In patients with positive serology for Chagas disease, different electrical injuries can occur during their evolution, and they differ according to the geographical distribution of Trypanosoma cruzi. Objectives. To determine which electrocardiographic lesions have seen in patients living in south of Salta city (Salta, Argentine). Materials and methods. A prospective observational study was conducted from 11/10/2013 to 02/29/2016, at the cardiology department of Pope Francisco Hospital located in southern part of Salta city. All patients underwent a complete clinical history, 12-lead electrocardiogram and diagnosed with Chagas disease by two positive serological reactions: HAI and Elisa. The International Consensus of Chagas disease 2010 was used. Statistical variable: the percentage was used. Results. We evaluated 400 patients with positive epidemiology for Chagas disease, 110 were finally diagnosed with Chagas disease; 59 (54%) female patients, the average age for both sexes was 47 years. Chronic Chagas disease without proven structural pathology occurred in 60 (55%) patients, average age 45 years. Chronic Chagas disease with structural damage 50 (45%) average age of 59 years, the most frequent electrocardiographic pattern in the analyzed population was LAHB + RBB. Conclusion. The most frequent electrocardiographic pattern in the analyzed population was LAHB + RBB, predominating in our consultation females patients.
