IMPLANT INFORMATION

IMPLANTING THE PULSE GENERATOR

Whichever lead conﬁguration is used for both pacing/sensing and deﬁbrillating ,

several considerations and cautions should be heeded. Such factors as

cardiomegaly or drug therapy may necessitate repositioning of the deﬁbrillating

leads or su bstituting 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.

CAUTION: Do not suture directly over the lead body as this may cause

structural damag e . Use the lead stabilizer to secu re th e lead lateral to the

venous entry side.

Step D: Take Bas eline Measurements

Once the leads are implanted, take baseline m easurements. Evaluate the

lead signals. If performing a pulse generator replacement procedure, existing

leads should be reevaluated, (e.g., signal amplitudes, pacing thresholds, and

impedance). The use of radiography may help ensure lead position and

integrity. If testing results are unsatisfactory, lead system repositioning or

replacement may be required.
