CONCLUSION
SCD is a major contributor to mortality in ESRD patients on HD, but the
arrhythmogenic mechanisms underlying SCD in this population remain
unclear. We have used CIED rhythm analysis to evaluate the differences
in VA burden between patients on HD and controls. We found no
differences in the prevalence of VA between the two groups, but control
patients were more likely to require device therapy. HD patients were
most likely to experience any VA in the 12 hours following their most
recent HD session compared to other intervals, but the majority of these
events were non-sustained. HD patients did not have higher atrial nor
ventricular pacing burden compared to controls. Larger studies including
HD patients with CIEDs are needed to continue advancing our
understanding of the precise pathophysiologic links between SCD,
arrhythmia, and ESRD.
