Longevity is also affected in the following circumstances:
• A decrease in pacing impedance may reduce longevity.
• 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 7 days.
• Five patient-initiated LATITUDE Communicator interrogations per week for a year reduces longevity by
approximately 29 days.
• An additional maximum-energy shock reduces longevity by approximately 16 days.
• An additional 6 months in Storage mode prior to implant will reduce longevity by 39 days. Assumes
implanted settings of 70 ppm LR L; DDD R mode; 15% atrium pacing; 100% biventricular pacing; 0.4 ms
pacing Pulse Width; 500 pacing Impedance; 2.5 V pacing pulse Amplitude (RA, RV); 3.0 V pacing
pulse Amplitude (LV).
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
specific to the implanted device.
