CAUTION
High output settings combined with very low lead impedance may
reduce the life expectancy of the pulse generator to less than 1 year.
Programming of pulse amplitudes, higher than 4.8 V, in combination
with long pulse widths and/or high pacing rates can lead to premature
activation of the replacement indicator
Table 23 shows the expected longevity (in months) from BOS to ERI for the Evia HF / HF-T pulse
generators. The programmer software for the Evia HF / HF-T pulse generators provides an estimated
time to ERI in months and years that is updated each time the device is reprogrammed. This estimation
allows the physician to understand the longevity effects of modifying programmed parameters.

Table 24: Remaining Expected Service Time
All service intervals, including the above-cited nominal pulse generator longevity, are based on
considerations that consider the battery discharge behavior and the hybrid circuit properties including
current consumption and replacement indicator.
