Brief summary

The purpose of this study is to determine if the hemodialysis procedure changes the risk for cardiac arrest in patients.

Detailed description

One-third to one-quarter of hemodialysis patients die of sudden cardiac death (SCD). The hemodialysis procedure may theoretically increase the risk of SCD. This study uses T wave alternans, a noninvasive marker of SCD, to objectively determine whether the hemodialysis procedure alters the risk of SCD in hemodialysis patients.
