NOTES: Pacing Therapy should be administered while connected to AC power with a battery installed for
backup so that pacing will not be interrupted in the event of either an AC power failure or the
battery losing its charge.
If you enter Pacing Mode, Sync settings are turned off.
If Paddles is selected for display in Wave Sector 2 and the device enters Pacer Mode, the Wave Sector
2 waveform automatically switches to None.
If Paddles is selected for display in Wave Sector 1 and the device enters Pacer Mode, the Wave Sector
1 waveform switches to Lead II.
If Pads is selected for the display in Wave Sector 2 and the device enters Demand Mode pacing, the
Wave Sector 2 waveform automatically switches to None.
If monitoring for an extended period of time, monitoring electrodes and multifunction electrode
pads may need to be changed periodically. Refer to the manufacturer's documentation for
replacement frequency.
Signals from TENS or ESU units can cause interference with the ECG which may impact pacing.
Pace Pulse Duration
You can configure the duration of the paced pulse in Configuration Mode to either 20 or 40 msec.
Confirm with your organization which setting best meets your clinical needs. If you select 20 msec,
you can select a current setting between 10-200 mA. If you select 40 msec, you can select a current
setting between 10-140 mA. See
