The purpose of this study is to assess the degree of cardiac electrical instability at various times in the dialysis cycle. The hypothesis is that longer time intervals between hemodialysis results in sympathetic and electrolyte-induced alterations in ventricular repolarization that can be measured non-invasively using microvolt T-wave alternans (TWA). This increase in cardiac electrical instability may serve as a link between the clinically observed periods of increased risk and the occurrence of sudden cardiac death.
