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.
Note
If you scroll to the bottom selection of the Waveform Source menu—either Add 
2nd Wave or Remove 2nd wave—the selection takes effect immediately and the 
monitor returns to the primary data display. 
Note
In the Waveform Source menu, either the source Lead or the waveform period 
can be highlighted. If the waveform period is highlighted, a second trace of the 
same source will be cascaded to double the period obtained from a single trace.
