Objective: Cardiac arrhythmias commonly occur in hemodialysis patients. QT dispersion (QTd=QTmax-QTmin) reflects heterogeneity of cardiac repolarization, and increased QTd is known to predispose the heart to ventricular arrhythmias and sudden cardiac death. The aim of our study was to assess the association of iron stores, reflected by transferrin saturation (TSAT) and ferritin, with the dispersion of corrected QT intervals (QTc) in patients undergoing hemodialysis.
