Projected Longevity From ERI to Erratic Pacing
The following tables show the estimated time from the ERI to erratic pacing for the Prodigy
pacemakers. Regardless of the patients programmed settings, virtually all (i.e., 99.9%) Prodigy DR,
Prodigy D, and Prodigy VDD pacemakers will achieve a minimum (min) of 3.0 months longevity after
ERI is set, while Prodigy SR and Prodigy S pacemakers will achieve a minimum (min) of 2.5 months
longevity after ERI is set. Additional longevity may be gained depending on the patient’s individual
pacing conditions. Note that the average (avg) time in the table below refers to the projected mean
longevity of pacemakers at the stated conditions.

* Current data show that combinations of extreme pacing conditions (high output values [≥ 5.0V] and high pulse widths or low
impedance values [300 ohms]) may increase the average projection in the DDDR/DDD modes.
