VNS Therapy SENTIVA M3000 Programmer Technical Manual page 27

CAUTION:
For generators capable of heartbeat detection, if AutoStim or Magnet
stimulation is programmed on, the Verify Heartbeat Detection feature
may be interrupted if AutoStim or Magnet stimulation is activated
during the Verify Heartbeat Detection process. In this case, "?? BPM"
will display on the screen. If "?? BPM" displays, LivaNova recommends
you temporarily disable all output currents for generators capable of
heartbeat detection (i.e. program to 0 mA) and retry the heartbeat
verification. After the calibration process is completed, you may
reprogram the output currents as appropriate.
To set the AutoStim Threshold:
The AutoStim Threshold is a setting on the Detection Tab that can be set from
20% to 70% (in 10% increments). This setting allows you to determine the
minimum heart rate change required for AutoStim, and should be tailored to
the individual patient. For the most sensitive detection and the smallest heart
rate change for stimulation, choose 20%. For the least sensitive detection and
thus the largest heart rate change for stimulation, choose 70%.
NOTE:
Additional guidance for how to program this patient-specific setting
can be found in the VNS Therapy System Physician's Manual.
