When the ERI point is reached, the following parameters are
switched to Nominal mode (listed in the table of programmable
parameters) until the end of the device's life:
! Mode
! Basic rate
! Rate hysteresis
! Rate response mode
! Smoothing
Other parameters remain as programmed.
When the ERI point is reached and under following conditions: VVI,
70 min
-1
, 0.4 ms, 500 Ohms, operation remaining before end of life is
approximately:
! 9.9 months with 2.5 V programming
! 7.6 months with 3.5 V programming
! 5.9 months with 5 V programming
! 4.1 months with 7.5 V programming
The pacing amplitudes actually available at ERI are:
! 2.4 V with 2.5 V programming
! 3.45 V with 3.5 V programming
! 4.5 V with 5 V programming
! 6 V with 7.5 V programming
8.3. EXPLANT
The pacemaker should be explanted in the following cases:
! End of life
! Confirmed malfunction
! Cremation of the patient (the pacemaker may explode if placed in
an incinerator)
! Patient death: for environmental reasons, the local regulation may
require the explantation of the devices containing a battery supply.
