Abstract

Aim: The incidence of atrial fibrillation is increased during hemodialysis (HD); however, the effects of hemodiafiltration (HDF) on atrial arrhythmias have not been evaluated. The prolongation of the P wave and P dispersion (Pd) can predict atrial arrhythmias. Methods: Data from 30 patients receiving HDF over a period of 3 months were collected; the same group of patients was then evaluated during treatment with conventional HD for at least another 3 months. Electrolyte values were obtained, and surface electrocardiograms (ECG), echocardiography, and Holter ECGs were performed. Results: The duration of the P wave and Pd increased significantly during HD. The left atrial diameter decreased significantly only during HDF. During HDF, the left atrial cross diameter measured at the beginning of the session was positively correlated with the incidence of supraventricular premature beats (p = 0.011, r = 0.4556). The decrease in left atrial diameter during HDF was negatively correlated with the incidence of supraventricular premature beats (p = 0.016, r = −0.43). During HDF, the changes in sodium and Pd were significantly positively correlated (p
