WARNING: When the elective replacement indicator (ERI) is set, the pacemaker will continue to
operate at ERI conditions for a minimum of 3.0 months for the Prodigy VDD pacemaker and a
minimum of 2.5 months for the Prodigy SR and Prodigy S pacemakers until the battery depletes.
NOTE: The values above are based on calculations using deliverable battery capacity. These values
are estimates of longevity projections from implant to ERI and are intended to assist the clinician in
understanding the effects of various pacing conditions on battery longevity. These values should not
be interpreted as precise numbers.
