8 Resting 12-Lead ECG Analysis
8.1 Resting 12-Lead ECG Analysis Introduction
The monitor can be configured with the Glasgow 12-lead resting ECG analysis algorithm. The monitor
incorporating the Glasgow algorithm is labeled with the logo of Glasgow as shown in
7.1ECG Introduction.
The Glasgow algorithm is intended for adult, pediatric, and neonatal patients.
8.2 Entering the 12-Lead Screen
To enter the 12-Lead screen, follow this procedure:
1. Select the ECG numeric area or waveform area to enter the
ECG dialog.
2. From the bottom of the
ECG dialog, select 12-Lead.
You can also enter the 12-Lead screen by following this procedure:
■Select the Screen Setup quick key → select Choose Screen → select ECG 12-Lead.
■Select Main Menu quick key → from the Display column select Choose Screen → select ECG 12-Lead.
• The ECG 12-Lead screen is available only when the Glasgow algorithm is configured (associated
module has the Glasgow label) and Lead Set is set to Auto or 12-Lead.
8.3 Initiating Resting 12-Lead ECG Analysis
Before initiating 12-lead ECG analysis, check that all electrodes are correctly connected to the lead wires and the
ECG trunk cable is properly connected. Check that patient information is correct. Keep the patient still.
To initiate 12-Lead ECG analysis, select
Analyze from the bottom left of the 12-Lead screen.
8.4 Changing 12-Lead ECG Analysis Settings
On the ECG 12-Lead screen, you can set the high frequency filter, baseline drift removal (BDR) filter, and the
waveform layout.
8.4.1 Setting the High Frequency Filter
The high frequency filter attenuates muscle artifact by restricting the included frequencies. The setting of the
high frequency filter is 35 Hz by default. To change the setting, follow this procedure:
1. On the ECG 12-Lead screen, select the ECG numeric area or waveform area to enter the
ECG dialog.
2. Select the
Setup tab.
3. Set
High-Freq Cut-off.
The high frequency filter is a low-pass filter. That is to say, signal frequencies higher than the set frequency are
filtered out. For example, if you set
High-freq Cutoff to 35 Hz, then signal below 35 Hz is kept in the signal and
signal exceeding 35 Hz is attenuated.
8.4.2 Setting the Baseline Drift Removal Filter
The baseline drift removal (BDR) filter 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 dialog.
