Pacemaker Longevity
Background
The Elective Replacement Indicator (ERI) establishes the point in time
when the physician should schedule replacement of the pacemaker as soon
as possible.
Elective Replacement Indicator
The Elective Replacement Indicator consists of a pacing mode and
distinctive rate, as follows:
■
Pacing Mode VVI
■
Lower Rate 65 ppm
When ERI is set due to battery depletion, the pacemaker will continue to
operate under elective replacement conditions unless the programmer
“Status Reset” command clears the ERI.
Time from ERI to Cessation of Pacing
From the point that the ERI is set, the pacemaker will continue to operate at
ERI conditions for a minimum of 3.0 months for Prodigy DR, Prodigy D
and Prodigy VDD pacemakers and 2.5 months for Prodigy SR and
Prodigy S pacemakers until the battery fully depletes. At full battery
depletion, erratic pacing will ensue. The patient should be scheduled for
immediate pacemaker replacement when the ERI is first detected.
