NOTE: If a 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 either a sutureable, steroid-eluting
pace/sense epicardial lead or sutureless epicardial pace/sense lead 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, and then tighten the setscrew onto the plug.
CAUTION: If a dual-chamber device is programmed to AAI(R), ensure that a functional RV lead is present. In
the absence of a functional RV lead, programming to AAI(R) may result in undersensing or oversensing.
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.
Implant t he leads via the surgical approach chosen.
When replacing a previously implanted pulse generator, it may be necessary to use an adapter to enable the
new pulse generator to be connected to the existing leads. When using an adapter, follow the connection
procedure described in the applicable adapter product data sheet. Always connect the adapter to the lead and
repeat threshold and sensing measurements before connecting the adapter to the pulse generator.
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
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.
• Connect the pace/sense lead(s) to a pacing system analyzer (PSA).
