Dialysis flowsheet data and dialytic cycle
For patients on HD, intradialytic flowsheet data was reviewed for
sessions occurring from the date of the patient’s first device
interrogation onward. Relationship between the dates of HD initiation
and CIED implantation was also recorded. Intradialytic flowsheet data
included the following: HD start time, HD end time, route of vascular
access, pre- and post-dialysis blood pressure, and target weight. For
patients initiated on HD after CIED implantation, VA events pre- and
post-HD initiation were recorded. Additionally, the timing of VA events
in relation to the most recent HD session was documented. Specifically,
the number of events occurring during HD were recorded, as were the
number of events occurring within each of the twelve-hour windows from
the time of HD end through more than 72 hours after HD end.
