2 Projected service life information

2.1 Projected service life for CRT-D devices

The projected service life in years for the device is shown in Table 1. The data is based on
pacing outputs programmed to the specified amplitude and 0.4 ms pulse width, 100%
biventricular pacing, the specified percentage of atrial pacing at 60 bpm and the remainder
at 70 bpm atrial tracking.

The projected service life estimates assume the default automatic capacitor formation
setting. As a guideline, each full energy charge decreases projected service life by
approximately 25 days. The service life of the device is affected by the programmed settings
for certain features, such as Pre-arrhythmia EGM storage.

Projected service life estimates are based on accelerated battery discharge data and device
modeling as specified. These values should not be interpreted as precise numbers.
