Current consumption of the OPTIMIZER Smart IPG is strongly dependent on the energy delivered by the CCM pulse train.
Safe Mode
Mode
Description
DOWN mode
When the device encounters conditions considered to be the
result of faulty device circuitry or software, it will switch to
DOWN mode. In DOWN mode, the device is completely
quiescent; CCM signals are not delivered and cardiac events are
not sensed. To take the device out of this mode, a
device reset
must be performed under physician supervision.

Characteristics
OOO
Standby mode: no events are sensed and no CCM impulse trains
are delivered
ODO-LS-CCM
Active mode where the device senses atrial, ventricular and
Local Sense events and is capable of CCM signal delivery
OVO-LS-CCM
Active mode where the device senses ventricular and local sense
events and is capable of CCM signal delivery
without the need
for the detection of atrial sense events.
