Key result
The haemodialysis process significantly increased ventricular repolarisation dispersion, with QT-c-D increasing from 53.40 ms predialysis to 67.59 ms postdialysis (p<0.001).
Why the study?
Does the haemodialysis process increase regional and transmyocardial repolarisation inhomogeneities in HD patients?

May heighten arrhythmia vigilance in HD sessions; leaves open whether electrolyte management mitigates risk in prospective trials.

Haemodialysis significantly increases ventricular repolarisation dispersion, which appears to be driven by acute changes in electrolytes and extracellular body water.
Jaroszyński et al. (2005) conducted an observational in Haemodialysis (n=32). Haemodialysis vs. Predialysis state and healthy controls was evaluated on Dispersion of the QT corrected interval (QT-c-D) (p=<0.001). The haemodialysis process significantly increased ventricular repolarisation dispersion, with QT-c-D increasing from 53.40 ms predialysis to 67.59 ms postdialysis (p<0.001).
