The effect of hemodialysis on Q-T interval on children with chronic renal failure.

The hemodialysis patients have a wide variety of electrocardiographic (ECG) abnormalities and, in certain instances; hemodialysis itself seems to be a cause of ECG changes and different kinds of dysrhythmias. The purpose of the study was to assess the effect of hemodialysis on QT and corrected QT (QTc) interval and QTc interval dispersion in patients with end-stage renal failure 10 min before (pre-HD) and 10 min after each hemodialysis (post-HD). An observational cross-section study was conducted on 30 patients'admitted to the dialysis unit in Abou El Ressh pediatric hospital along a period of 6 months starting from October 2008.
