About pacemakers and ECG monitoring
If the patient being monitored has a pacemaker, the monitor detects and can indicate the
occurrence of pacemaker signals. If the Pacer Indicator setting is ON, the monitor displays
and prints vertical dashed lines to indicate detected pacemaker signals. If Pacer Indicator
is OFF, the monitor continues to detect the pacemaker signals but does not display or
print the pacer markers.
To enable or disable the display of pacer indicators
1. Access the Setup menu. (See “To access the setup menus” on page 37.)
2. Highlight ECG.

3. Highlight Pacer indicator and press or to highlight Off or On.
4. To exit the Setup menu, press or , or highlight Exit and press .
WARNING Signals differ between pacemakers. The Association for
Advancement of Medical Instrumentation (AAMI) cautions that “in some devices,
rate meters may continue to count the pacemaker rate during occurrences of
cardiac arrest or some arrhythmias. Do not rely entirely upon rate meter alarms.
All pacemaker patients should be kept under close or constant observation.”
WARNING Use of respiration monitoring by impedance pneumography can
affect the operation of some pacemakers. If pacemaker operation is affected, turn
off respiration pneumography. (See
Figure 63 on page 57.)
WARNING Always use fresh ECG electrodes and make sure the ECG cable lead
wires make good connections. The presence of pacer-like noise can cause the
displayed heart rate to be erratic even though the ECG trace might look
undistorted with the pacer indicator off.
Note If the pacemaker signal is strong enough, the monitor displays it as a waveform
spike. This is true with Pacer indicator ON or OFF.
In accordance with the Pacer Pulse Rejection specification ( “Pacer pulse
rejection” on page 145.), pacemaker pulses are not counted as heartbeats
whether Pacer Indicator is On or Off.
Noise on the ECG signal might be detected as pacer signals, causing the pacer
indicator to appear on the display. If you do not need to indicate pacemaker
signals, turn off the pacemaker indicator for a better ECG waveform display.
