Introduction: Upper gastrointestinal bleeding is a common cause of medical attention, with a mortality in Mexico of 8.5%. Our main objective was to determine the association of this pathology with cardiac conduction disturbances and other clinical variables. Material and methods: We reviewed the electrocardiograms and files of patients attended for acute upper gastrointestinal bleeding at the Internal Medicine Service of the National Medical Center "20 de Noviembre", they must have had a previous normal electrocardiogram; excluding those with severe hemorrhage, this means, presented with hypotension managed with intravenous fluids and/or vasoactive drugs. Statistical analysis was performed using the SPSS10 program. Results and conclusions: 56 patients were included, 34 women and 22 men; 60.7% were older than 70 years. We report an association between acute upper gastrointestinal bleeding and electrocardiographic changes, principally right bundle branch block in 30.35% of cases.

Keywords : Bundle-branch block; Electrocardiogram; Upper gastrointestinal bleeding.
