- Additional Technical Information
Selection of lead configuration and specific surgical procedures is a matter of professional judgment. The
following leads are available for use with the pulse generator depending on the device model.
• ENDOTAK endocardial cardioversion/defibrillation and pacing lead system
• Ventricular endocardial bipolar lead
• Atrial bipolar lead
• Superior vena cava lead coupled with a ventricular patch lead
• Two-patch epicardial leads configuration
CAUTION: The absence of a lead or plug in a lead port may affect device performance. If a lead is not used,
be sure to properly insert a plug in the unused port, and then tighten the setscrew onto the plug.
CAUTION: Do not suture directly over the lead body, as this may cause structural damage. Use the suture
sleeve to secure the lead proximal to the venous entry site to prevent lead movement.
Whichever lead configuration is used for both pacing/sensing and defibrillating, several considerations and
cautions should be heeded. Factors such as cardiomegaly or drug therapy may necessitate repositioning of the
defibrillating leads or s ubstituting one lead for another to facilitate arrhythmia conversion. In some instances,
no lead configuration may be found that provides reliable arrhythmia termination at energy levels available from
the pulse generator. Implantation of the pulse generator is not recommended in these cases.
Implant the leads via the surgical approach chosen.
NOTE: Should lead performance changes occur which cannot be resolved with programming, the lead
may need to be replaced if no adapter is available.
Step D: Take Baseline Measurements
Once the leads are implanted, take baseline measurements. Evaluate the lead signals. If performing a pulse
generator replacement procedure, existing leads should be reevaluated, (e.g., signal amplitudes, pacing
