Changes in QT intervals in patients with end-stage renal disease before and after hemodialysis

Saudi Journal of Kidney Diseases and Transplantation, 2010
Increased dispersion of QT intervals is known to predispose to ventricular arrhyth-mias and sudden cardiac death. To assess the effect of hemodialysis (HD) on QT and corrected QT (QTc) intervals and their dispersions in chronic hemodialyzed patients we ...
