Mexico is among the countries with the highest number of patients on kidney replacement therapy (RRT). Despite this, the incidence and prevalence of CKD in Mexico is unknown, due to the lack of a national registry as a result we do not know risk factors associated to this population.
Electrocardiographic abnormalities or arrhythmias are among the most frequent cardiovascular pathologies, being the first cause of death during the first month in RRT. That is why the present study aims to identify the prevalence of arrhythmias in a group of Mexican patients on hemodialysis as well as their associated risk factors.


A non-experimental, observational, descriptive, and cross-sectional study was carried out in the period from March to July 2020 with Mexican patients older than 18 years in maintained hemodialysis. The electrocardiograms and blood test analysis were taken on the day of hemodialysis therapy.


The mean age of the population was 42.37 years, 57% were male. Arrhythmias were found in 50 patients (41.67%), the prevalence of arrhythmias found was bundle branch block (17.50%), sinus tachycardia (12.50%), sinus bradycardia (7.50%), atrial fibrillation (2.50%), extrasystoles (1.67%). A significant difference in mean ages was found between patients with (47.14) and without arrhythmia (38.97) (P = 0.041). A history of heart disease (OR 7.54 95% CI 1.05-184.7), and the diagnosis of chronic renal failure secondary to diabetic nephropathy (OR 2.5459 95% CI 1.1026- 5.8785) were identified as risk factors. The diagnosis of chronic renal failure secondary to arterial hypertension was no related as risk factor (p=0.86). No laboratory study was identified as a risk or protective factor for the development of arrhythmia either the vascular access type.


The studied population presented similar characteristics to the described previously, a high prevalence of electrocardiographic abnormalities was identified, laboratory studies were not related to the presence of arrhythmias. History of heart disease and kidney disease secondary to diabetic nephropathy were associated as a risk factors, while the presence of arterial hypertension was not identified as risk factor.
