Abstract: Introduction: cardiovascular complications are the leading causes of death in patients with chronic kidney disease from stages 2 or 3 to stage 5 (end stage renal disease), accounting for about 50% of deaths in this group of patients. The disease in stage 5 is characterized by glomerular filtration rate lower than 15 mL/min/1.73m² and its main causes are hypertension and Diabetes mellitus type 2. Objective: to describe the changes in the electrocardiogram of patients with chronic kidney disease stage 5 at the moment they start dialysis and correlate them with the underlying disease that caused chronic kidney disease. Results: the electrocardiograms of 199 patients from a single dialysis center in a 4-year period were evaluated. Most patients have chronic kidney disease caused by Diabetes mellitus type 2 (36.5%), hypertension (30%) and glomerulopathies (12%). We observed only 12% of electrocardiograph exams with normal tracing. The most common changes were the left atrial enlargement (31%), left ventricular hypertrophy (30%), altered ventricular depolarization by hyperkalemia (26%) and QTc prolonged interval. Left ventricular hypertrophy was more prevalent in patients with hypertension as a cause of chronic kidney disease and the strain fairly common pattern (47% of cases with left ventricular hypertrophy). Conclusion: the electrocardiograph changes are very prevalent in patients with stage 5 chronic kidney disease and must be known by the professionals who take care of them.
