Abstract

Background. Analysing a 12-lead surface electro-cardiogram (ECG), the inter-lead variability of the P wave interval, i.e. P wave dispersion, is defined as the difference between the maximum and the minimum P wave duration. Our aim was to assess the effect of haemodialysis on P wave duration and dispersion in non-diabetic patients with end-stage renal failure on chronic haemodialysis. Methods. Twenty-eight patients (14 men and 14 women, mean age 58 ± 16 years, average duration of dialysis 4.5 ± 2.8 years) were examined. Prior to haemodialysis, echocardiography (M-mode and two-dimensional) was performed. Haemodialysis sessions were carried out with polysulfone dialysers and bicarbonate dialysate fluids. Twelve-lead ECGs were recorded at the beginning, 15 and 30 min after starting dialysis, at the end, and 2 h after completion of each session. Ionic parameters were checked during the study. P wave durations were measured with calipers in three consecutive complexes of each lead by one observer. Results. P maximum was 58 ± 16 ms at the beginning, and showed an increase by the end of dialysis to 98 ± 8.9 ms (P <0.0001). Pre-dialysis P dispersion was 23 ± 10 ms and increased to 41 ± 16 ms by the end of the sessions (P <0.0001). In patients with a left atrial diameter larger than 45 mm, P dispersion increased from 23 ± 11 to 53 ± 10 ms (P <0.0003) by the end of the sessions. Conclusions. According to our results, ionic imbalance and dialysis itself may cause changes in P duration and dispersion simultaneously.
