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.
