The longevity expectations, which account for the energy used during manufacture and storage, apply at the
conditions shown in the table along with the following:
• Assumes 60 ppm LRL, ventricular and atrial settings of 2.5 V pacing pulse Amplitude and 0.4 ms pacing
pulse width; RA Imp edance 500 ;sensorsOn.
• Projected longevity is calculated assuming 3 maximum energy charging cycles per year, including
automatic capacitor re-forms and therapeutic shocks. For the final year of device service, an additional
5 charging cycles are assumed to account for additional automatic capacitor re-forms as the device
approaches the Explant indicator. These calculations also assume 3-channel EGM Onset is set to O n,
and that the pulse generator spends 6 months in Storage mode during shipping and storage.
