IMPLANT INFORMATION

IMPLANTING THE PULSE GENERATOR

NOTE: If the coronary venous lead cannot be used and the physician’s

medical judgment indicates that a limited left thoracotomy is justiﬁed to place

an epicardial lead, the use of sutureable, steroid-eluting pace/sense epicardial

leads is recommended.

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.

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

several considerations and cautions should be heeded. Such factors as

cardiomegaly or drug therapy may necessitate repositioning of the deﬁbrillating

leads or substituting on e lead for another to facilitate arrhythmia conversio n.

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 stabilize r to secure the lead lateral to the

venous entry side.

Step D: Take Bas eline 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 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.
