EOS Indication

The Prolonged Service Period (PSP) is the time between the RRT and EOS. The PSP is defined as 3 months assuming the following conditions: 100% DDD pacing at 60 min-1, 2.5 V atrial and RV pacing amplitude; 0.4 ms pulse width; 600 Ω pacing load; and 6 full-energy charges. The EOS may be indicated before the end of 3 months if the device exceeds these conditions.


Recommended Replacement (RRT)

Battery voltage less than or equal to 2.63V on 3 consecutive daily automatic measurements.
