BACKGROUND
Due to rapid changes in volume and electrolyte concentration following hemodialysis, some electrocardiographic (ECG) changes or arrhythmias can be seen. This study aims to assess electrocardiographic (ECG) QRS axis changes and other ECG parameters after the hemodialysis (HD) in patients with end-stage renal disease (ESRD).

METHODS
Patients with sinus rhythm and undergoing chronic HD treatment without cardiovascular disease were included to the study. Blood samples, 12-lead electrocardiograms, and echocardiograms were recorded immediately before and at the end of the HD session. The QRS axis and other electrocardiographic, echocardiographic, electrolyte parameters, and volume changes were analyzed.

RESULTS
Fourty-six individuals(65% male) with mean age 52 ± 15 years were enrolled the study. Serum urea, creatinine, potassium and BNP concentrations significantly decreased after HD and serum calcium levels significantly increased after HD. The body weight significantly decreased after HD. There was no significant difference in the QRS duration, PR interval, P wave axis, QRS axis, QT and QTc interval with HD. Based on the comparison of variables according to the any QRS axis change after hemodialysis, there was no significant difference in biochemical values, HD time, ultrafiltration volume, left ventricular ejection fraction, and other echocardiographic findings.

CONCLUSION
As ESRD and HD are complex and dynamic processes, and the change in the QRS axis is rarely emphasized in these patients. In our study, there was not significant change the QRS axis with HD in patients without cardiovascular disease.
