EOL Indication

EOL device status is defined as three months following an ERI indication assuming the following post-ERI conditions: 100% DDD pacing at 60 min-1, 2.5 V, 0.4 ms; 500 Ohm pacing load; and six full-energy charges. EOL may be indicated before the end of three months if the device exceeds these conditions.


Elective Replacement (ERI)

Battery voltage less than or equal to 2.61 V on three consecutive daily automatic measurements.
