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.
