NOTE
•
If D12L is enabled, you cannot select the derived leads as ECG1 or ECG2.
10.6.4.2 Setting the ECG Waveform Layout
To set the ECG waveform layout, follow this procedure:
1. 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.
10.6.4.3 Changing ECG Waveform Size
If the ECG waveform is too small or clipped, you can change its size by selecting an appropriate
Gain
setting. To
do so, follow this procedure:
1. Select the ECG numeric area or waveform area to enter the
ECG
menu.
2. Select the
Setup
tab.
3. Select
ECG Gain
to set the size of each ECG waveform.
4. If more than three ECG waveforms are displayed, select the
More Leads
tab, and then select
ECG Gain
to
change the sizes of other ECG waveforms. If you select
Auto
, the monitor automatically adjusts the size of
the ECG waveforms.
10.6.4.4 Changing Va and Vb Labels
When monitoring ECG with 6-leadwire. You can change the labels of Va and Vb leads. To do so, follow this
procedure:
1. Select the ECG numeric area or waveform area to enter the
ECG
menu.
2. Select the
Setup
tab.
3. Set
Va
and
Vb
according to the Va and Vb electrode sites. Default settings are
Va
and
Vb
.
10.6.4.5 Changing ECG Waveform Speed
To change ECG waveform speed, follow this procedure:
1. Select the ECG numeric area or waveform area to enter the
ECG
menu.
2. Select the
Setup
tab.
3. Set
Speed
.
10.6.4.6 Setting the ECG Filter
To set the ECG waveform filter mode, follow this procedure:
1. Select the ECG numeric area or waveform area to enter the
ECG
menu.
2. Select the
Setup
tab.
3. Set
Filter
.
◆
Diagnostic
: use when diagnostic quality ECG is required. The unfiltered ECG waveform is displayed so
that changes such as R-wave notching or discrete elevation or depression of the ST segment are
visible.
◆
Monitor
: use under normal measurement conditions.
