3. Print and review the Quick Notes report, and retain it in your files for future
reference.
4. For episodes of interest, review the Arrhythmia Logbook screen and print
episode details and store d electrogram information.
5. It is important to clear the therapy counters so that at the next follow-up
session the most recent episode data will be displayed.
CAUTION: Verify with a conversion test that the patient’s tachyarrhythmias
can be detected and terminated by the pulse generator system if the patient’s
status has changed or parameters have been reprogrammed.

Sensitivity Adjustment
The Sensitivity Adjustment feature allows you to shift the atrial sensing range to
make it less sensitive (i.e., a larger signal would be required for the device to
detect). It allows shifting the ventricular sensing range to make it less or more
sensitive. While th e Nomina l setting is p rima rily indicated fo r both a trial and
ventricular sensing, an adjustment can be made if, in a rare situation, atrial or
ventricular oversensing/undersensing has been observed post-implant (i.e.,
inhibition of bradycardia pacing or inappropriate tachy therapy).
Should it become necessary to adjust the sensing range in a chamber,
always choose the setting that allows the greatest sensitivity, but resolves
oversensing/undersensing:
• To reduce oversensing, program the sensitivity to a higher value.
• To reduce undersensing, program the sensitivity to a lower value.
After any change to sensitivity, evaluate for appropriate sensing for both
bradycardia pacing and tachycardia detection .
If proper sensing cannot be restored with an adjustment or if any undersensing
is observed after making a change, consider repositioning the lead or implanting
a new sensing lead and then programming the setting back to nominal.
CAUTION: Following any sensing range adjustment or any modifi cation of
the sensing lead, always v erify appropriate sensing.
