Key result
Hemodialysis and CAPD were associated with significantly higher rates of QT interval dispersion compared with healthy controls (p < 0.05).
Why the study?
Does hemodialysis or continuous ambulatory peritoneal dialysis increase QT dispersion in end-stage renal disease patients compared to healthy controls?

Increased QT dispersion in dialysis patients may flag arrhythmia vulnerability; cross-sectional data leave causality and outcomes open.

Does hemodialysis or continuous ambulatory peritoneal dialysis increase QT dispersion in end-stage renal disease patients compared to healthy controls?
p-value: p=< 0.05
Both hemodialysis and CAPD patients exhibit increased QT dispersion compared to healthy controls, suggesting a higher tendency for cardiac arrhythmias in end-stage renal disease regardless of dialysis modality.
Kantarcı et al. (2002) conducted a cross-sectional in End-stage renal disease (n=60). Hemodialysis and CAPD vs. Healthy volunteers was evaluated on QT interval dispersion (p=< 0.05). Hemodialysis and CAPD were associated with significantly higher rates of QT interval dispersion compared with healthy controls (p < 0.05).
