Key result
Hemodialysis sessions significantly increased P wave dispersion at the 2nd hour compared to predialysis values (41 vs. 21 ms, p<0.001).
Why the study?
Does a hemodialysis session increase P wave dispersion in patients undergoing chronic hemodialysis?
Observational (n=25)
Does a hemodialysis session increase P wave dispersion in patients undergoing chronic hemodialysis?
Absolute Event Rate: 41% vs 21%
p-value: p=<0.001
P wave dispersion, an electrocardiographic marker of paroxysmal atrial fibrillation, transiently increases during hemodialysis sessions and is predicted by predialysis diastolic blood pressure, serum potassium, and ultrafiltration amount.

May signal transient peridialytic AF vulnerability; hypothesis-generating and should not yet change practice.
Özben et al. (2009) conducted an observational in Hemodialysis (n=25). Hemodialysis session vs. Predialysis (baseline) was evaluated on P wave dispersion (PWD) (p=<0.001). Hemodialysis sessions significantly increased P wave dispersion at the 2nd hour compared to predialysis values (41 vs. 21 ms, p<0.001).
