The clinical significance of hyperkalaemia-associated repolarization abnormalities in end-stage renal disease
Nephrology Dialysis Transplantation, 05/21/2012
Green D et al. – The reason for the variability in T–wave changes is not clear. The ratio of precordial T–wave to R–wave amplitude is a more specific measure than tenting but both are poorly sensitive at detecting hyperkalaemia. The greater risk for sudden death may represent a susceptibility to cardiac arrhythmia during repolarization.
