Elective Generator Change
After permanent pacemaker or device implantation, regular follow-up in a pacemaker clinic or transtelephonic follow-up is mandatory. The tests that should be performed include an assessment of battery life and time to elective replacement. The latter is assessed by the elective replacement indicator (ERI) for each device. The latter usually allows 6 months or more to arrange device replacement before end-of-life (EOL) parameters are reached when imminent replacement must take place in order to avoid loss of output and potentially serious clinical events.
