Haemodialysis increases QT(c) interval but not QT(c) dispersion in ESRD patients without manifest cardiac disease.
HD has been reported to determine an increase in QTc interval and QTc dispersion (QT(max)-QT(min))-risk factors that predispose to severe ventricular arrhythmias and sudden death. However, most studies have included end-stage renal disease (ESRD) patients with significant heart pathology. We therefore aimed to study the impact of a single HD session in subjects without manifest cardiac disease. ⋯ Haemodialysis increases the QTc interval in ESRD patients, mainly related to rapid changes in electrolyte plasma concentrations. However, the impact on QTc dispersion is less important in the absence of significant coexisting cardiac disease.
