Programmers—Use only <strong>BIOTRONIK</strong> ICS 3000 programmers to<br />
communicate with the device.<br />
Sealing System—Failure to properly insert the torque wrench into the<br />
perforation at an angle perpendicular to the connector receptacle may<br />
result in damage to the sealing system <strong>and</strong> its self‐sealing properties.<br />
Defibrillation Threshold—Be aware that changes in the patient’s<br />
condition, drug regimen, <strong>and</strong> other factors may change the defibrillation<br />
threshold (DFT) which may result in non‐conversion <strong>of</strong> the arrhythmia<br />
post‐operatively. Successful conversion <strong>of</strong> ventricular fibrillation or<br />
ventricular tachycardia during arrhythmia conversion testing is no<br />
assurance that conversion will occur post‐operatively.<br />
Manual Shocks—User‐comm<strong>and</strong>ed shocks may be withheld if the<br />
ICD⁄CRT‐D is already busy processing a manual comm<strong>and</strong> or the Battery<br />
Status is low.<br />
Charge Time—When preparing a high energy shock the charge circuit<br />
stops charging the capacitors after 20 seconds, <strong>and</strong> delivers the stored<br />
energy as shock therapy. After the device reaches ERI the stored energy<br />
may be less than the maximum programmable energy for each shock.<br />
Programming W<strong>and</strong> Separation Distance—The w<strong>and</strong> (with magnet)<br />
must not be placed closer than 2 cm to the device (implanted or out <strong>of</strong><br />
the box). Programming w<strong>and</strong> (with magnet) distance closer than 2 cm<br />
may damage the device.<br />
Shipment Mode—The shipment mode is a factory set mode that<br />
controls the charge current <strong>of</strong> automatic capacitor reformations.<br />
This mode controls the charge current to avoid temporary low battery<br />
readings. The shipment mode is automatically deactivated as soon as<br />
electrophysiological tests (e.g., Impedance measurement) have been<br />
performed. To ensure delivery <strong>of</strong> programmed shock energy, make sure<br />
shipment mode is disabled prior to completion <strong>of</strong> implant procedure.<br />
Shock Therapy Confirmation—Programming CONFIRMATION to OFF<br />
may increase the incidence <strong>of</strong> the ICD⁄CRT‐D delivering inappropriate<br />
shocks.<br />
Shock Impedance—If the shock impedance is less than twenty‐five<br />
ohms (25 Ω), reposition the lead system to allow a greater distance<br />
between the electrodes. Never implant the device with a lead system<br />
that has measured shock impedance <strong>of</strong> less than twenty‐five ohms<br />
(25 Ω). Damage to the device may result.
