If Multipoint LV Pacing (MP) is set to ON, an additional LV pacing vector is activated.
Consequently, the device longevity is reduced from 0.8 to 1.6 year dependent on the device
operating under the conditions described in the tables above, with MP activated for the
entire lifetime of the device from implant to explant, with the same LV pacing parameters (LV
amplitude, LV pulse width) and impedance applied on both LV vectors (MP1 and MP2).
1h of additional RF programming session reduces the device longevity from 1 to 2 weeks
depending on the device functioning mode (no pacing, 100% pacing). The mean longevity as
a function of shocks delivered at maximum energy, with and without pacing, is as follows:
The mean longevity as a function of yearly remote follow-ups
1
, with and without pacing, is as
follows:
1. An excessive number of remote follow-ups can have a non-negligible impact on device
longevity.
