ECG settings in Advanced Configuration -
The five settings in the Advanced Configuration
menu associated with the ECG are listed in this
table:
Advanced Configuration
ECG setting
ECG gain
ECG lead set
ECG speed
ECG bandwidth
Second trace
selection
You can change the ECG settings in Advanced
Configuration:
• Press the
Date/Time
• Press
Trend.
• Use either
button to highlight ECG
Select
gain, ECG lead set , ECG speed, ECG
bandwidth, or Second trace selection.
• Use the
button to change any of these
Set
values.
• Press

ECG gain - The height of the vertical ruler that
appears to the left of the ECG waveform
indicates a 1 mV amplitude and is 10 mm high if
10 mm/mV gain is chosen. When automatic
gain is selected the ruler height will vary, but it
will always indicate a 1 mV signal size. The
ruler size is automatically increased or decreased
to scale to a particular set of waves, but the
vertical line still indicates the same amplitude of
1 mV.
ECG lead set - The Atlas Monitor allows for
both 3 wire and 5 wire ECG lead sets.
Possible values

10 mm/mV
3 wire | 5 wire
6.25 | 12.5 | 25 mm/s

button.
Note: When using 3 wire leads, the ECG lead
set must be set correctly. Incorrect results
and noisy waveforms can be obtained if the
system is configured for 5 wire leads when
using 3 wire leads.
ECG speed - The amount of ECG waveform
shown on the CRT is determined by the trace
speed. A slower trace speed means more
seconds of waveform are shown on the CRT.
ECG bandwidth - The ECG waveform can be
displayed and printed in either Monitor or
Extended bandwidth. Monitor mode allows for
a clearer picture of the waveform by filtering out
noise. Extended mode, usually used with
cardiac paced patients, shows the finer nuances
of ECG waveform, facilitating the detection of
conditions such as ischemia.
Note: Detection of ischemia is the interpretation
of the clinician only, the Atlas Monitor does
not provide automated ischemia detection.
Note: It is normal for the ECG baseline to
wander slightly in Extended bandwidth.
Pacemaker signals – The Atlas Monitor
displays pacemaker signals exactly as they are
captured. There is no option to display symbolic
pace indications. Use Extended bandwidth for
enhanced display of pacemaker signals.
