Lumax Technical Manual 9
ERI (Elective Replacement Indicator) - Upon reaching ERI, the
battery has sufficient energy remaining to continue monitoring for
at least three months and to deliver a minimum of six maximum
energy shocks. After this period (EOS), all tachyarrhythmia
detection and therapy is disabled. Bradycardia functions are still
active at programmed values until the battery voltage drops below
1.75 volts.
Magnets - Positioning of a magnet or the programming wand
over the ICD/CRT-D will suspend tachycardia detection and
treatment. The minimum magnet strength required to suspend
tachycardia treatment is 1.8 mT. When the magnet strength
decreases to less than 1 mT, the reed contact is reopened.
Programmed Parameters – Program the device parameters to
appropriate values based on the patient’s specific arrhythmias
and condition.
Programmers - Use only BIOTRONIK ICS 3000 or Renamic
programmers to communicate with the device.
Sealing System - Failure to properly insert the torque wrench
into the perforation at an angle perpendicular to the connector
receptacle may result in damage to the sealing system and its
self-sealing properties.
Defibrillation Threshold - Be aware that changes in the patient’s
condition, drug regimen, and other factors may change the
defibrillation threshold (DFT) which may result in non-conversion
of the arrhythmia post-operatively. Successful conversion of
ventricular fibrillation or ventricular tachycardia during arrhythmia
conversion testing is no assurance that conversion will occur
post-operatively.
Manual Shocks – User-commanded shocks may be withheld if
the ICD/CRT-D is already busy processing a manual command or
the Battery Status is low.
Charge Time - When preparing a high energy shock the charge
circuit stops charging the capacitors after 20 seconds, and
delivers the stored energy as shock therapy. After the device
reaches ERI the stored energy may be less than the maximum
programmable energy for each shock.
