Background

Chronic kidney disease (CKD) is a current public health problem that has increased over the years. In Mexico, the incidence and prevalence of types of arrhythmias in CKD patients undergoing hemodialysis have not been studied, nor have risk factors associated with their development been identified. The objective of this study was to determine the frequency of arrhythmias in patients with CKD undergoing hemodialysis and to evaluate their overall health status to identify risk factors associated with the development of these electrocardiographic changes both before and after hemodialysis.

Methods

A descriptive, observational, prospective study was conducted at Hospital Universitario Puebla from May 2023 to April 2024. A systematic search identified 58 CKD patients undergoing hemodialysis. Clinical, laboratory, and pre- and post-hemodialysis electrocardiogram data were collected.

Results

The analysis included 58 patients with a mean age of 63.75 years; 51.72% were male. The most common arrhythmias were atrioventricular block (10.3%), bundle branch block (9.5%), prolonged QT interval (9.5%), and sinus bradycardia (8.6%). Older age groups were more predisposed to prolonged QT interval, while younger age groups had a higher prevalence of atrioventricular block. A history of heart disease and kidney disease secondary to diabetic nephropathy were associated as risk factors (p=0.03). The presence of arterial hypertension was not identified as a risk factor (p=0.65).

Conclusion

Atrioventricular block was the most common arrhythmia in hemodialysis patients. The types of arrhythmias observed in our CKD population were not as prevalent as reported in other populations.
