Setting the Baseline Drift Removal
The baseline drift removal (BDR) suppresses most baseline drift interference and also is able to preserve the
fidelity of the ST-segment level. BDR is switched on by default. To set the BDR, follow this procedure:
1.
On the ECG 12-Lead screen, select the ECG numeric area or waveform area to enter the
ECG
menu.
2.
Select the
Setup
tab.
3.
Switch on or off
Baseline Drift Removal
. If BDR is switched off, the 0.05 Hz high pass filter is used.
NOTE
•
BDR introduces around 1-second delay. We recommend using BDR except when the delay is
unacceptable.
9.4.3
Setting the 12-Lead Waveform Layout
To set the 12-lead waveform layout, follow this procedure:
1.
On the ECG 12-Lead screen, select the ECG numeric area or waveform area to enter the
ECG
menu.
2.
Select the
Setup
tab.
3.
Set
Waveform Layout
.
◆
Standard
: the waveform sequence is I, II, III, aVR, aVL, aVF, V1, V2, V3, V4, V5, V6.
◆
Cabrera
: the waveform sequence is aVL, I, -aVR, II, aVF, III, V1, V2, V3, V4, V5, V6.
For the Glasgow algorithm, the sequence of the chest leads depends on the setting of
V3 placement
. If
V3
placement
is set to
V4R
, the sequence of chest leads is V4R, V1, V2, V4, V5, V6.

Glasgow Resting 12-lead ECG Analysis Algorithm Settings
For the Glasgow algorithm, besides filter mode, BDR, and waveform layout, you can also perform the following
operation:
■
Editing patient information
■
Changing tachycardia and bradycardia thresholds.
■
Setting the 12-lead ECG report
9.5.1
Editing Patient Information (For Glasgow Algorithms)
Some patient information may directly affect ECG analysis. Complete and correct patient information is helpful
for accurate diagnosis and treatment of the patient. Enter patient information before taking an ECG
measurement.
To enter patient information, follow this procedure:
1.
On the ECG 12-Lead screen, select
Setup
to enter the
12-Lead Setup
menu.
2.
On the
Patient Demographics
page, input or edit patient information.
NOTE
•
Check that patient information is correct before resting 12-lead analysis.
•
We recommend using pediatric lead placement V4R, V1, V2, V4 - V6 if the patient is under 16 years of
age. Please record V4R using the V3 electrode. Also set V3 Electrode to V4R. This is a normal practice
for a patient of this age.
