May signal transient repolarization instability after hemodialysis in ESRD; hypothesis-generating and should not change practice without prospective confirmation.
Does a single haemodialysis session increase corrected QT dispersion in stable subjects with end stage renal failure?
Haemodialysis significantly increases corrected QT dispersion, suggesting increased inhomogeneous ventricular repolarisation and potential arrhythmia risk.
Howse et al. (2002) studied this question.
