WARNING
Resuscitation Availability - Do not perform induction testing
unless an alternate source of patient defibrillation such as an
external defibrillator is readily available. In order to implant
the ICD/CRT-D system, it is necessary to induce and convert
the patient’s ventricular tachyarrhythmias.
CAUTION
Pacing Threshold - Testing of the pacing threshold by the
ICD/CRT-D system should be performed with the pacing rate
programmed to a value higher than the patient's intrinsic rate.
Defibrillation Threshold - Be aware that the 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.
Electromagnetic interference (EMI) signals present in
hospital and medical environments may affect the function of
any ICD/CRT-D or pacemaker. The ICD/CRT-D is designed
to selectively filter out EMI noise. However, due to the variety
of EMI signals, absolute protection from EMI is not possible
with this or any other ICD/CRT-D.
The ICD/CRT-D system should have detection and therapy
disabled prior to performing any of the following medical
procedures. In addition, the ICD/CRT-D should be checked
after the procedures to assure proper programming:
Electrocautery - Electrosurgical cautery could induce
ventricular arrhythmias and/or fibrillation, or may cause
device malfunction or damage. If use of electrocautery is
necessary, the current path and ground plate should be kept
as far away from the pulse generator and leads as possible
(at least 6 inches (15 cm)).
