QTc dispersion in haemodialysis patients with cardiac complications.

Abstract

QTc dispersion (Maximum - Minimum QTc interval on a standard 12-lead electrocardiogram (ECG)) is a useful predictor of tachyarrhythmic events and related sudden cardiac death. Recent studies have reported that QTc dispersion is prolonged in patients receiving haemodialysis (HD), and it is often further prolonged following HD treatment. In the present study, we examine whether the patients who are susceptible to prolongation of QTc dispersion by HD are prone to life-threatening cardiovascular events and related deaths.
