Longevity is also affected in the following circumstances:
A decrease in pacing impedance may reduce longevity.
For Extended Longevity (EL) devices, when the R espiratory Sensor is programmed Off for the life of the
device, longevity is increased by approximately 4.5 months.
For MINI devices, when the Respiratory Sensor is programmed Off for the life of the device, longevity is
increased by approximately 2 months.
When Patient Triggered Monitor is programmed to On for 60 days, longevity is reduced by approximately
5 days.
One hour of additional telemetry reduces longevity by approximately 9 days.
Five patient-initiated LATITUDE Communicator interrogations per week for a year reduces longevity by
approximately 39 days.
For Extended Longevity (EL) devices, an additional maximum-energy shock reduces longevity by
approximately 21 days.
For MINI devices, an additional maximum-energy shock reduces longevity by approximately 23 days.
An additional 6 months in Storage mode prior to implant will reduce longevity by 54 days. Assumes
implanted settings of 60 ppm LRL, 2.5 V pacing pulse Amplitude and 0.4 ms pacing Pulse Width; 500
pacing Impedance; 50% pacing.
Device longevity may also be affected by:
Tolerances of electronic components
Variations in programmed parameters
Variations in usage as a result of patient condition
Refer to the PRM Summary and Battery D etail Summary screens for an estimate of pulse generator longevity
specic to the implanted device.
