12 Resting 12-Lead ECG Analysis
12.1 Resting 12-Lead ECG Analysis Introduction
The monitor can be configured with either Glasgow 12-lead ECG analysis algorithm or Mindray 12-lead ECG
analysis algorithm.
The Glasgow algorithm is intended for adult, pediatric, and neonatal patients. The Mindray algorithm is intended
for adult patients only.
The MPM module providing the 12-lead ECG analysis function has a 12-lead label. The MPM module
incorporating the Glasgow algorithm is labelled with the logo of Glasgow.
For more information on the Glasgow algorithm, refer to 12-Lead ECG Interpretive Program Physician’s Guide (PN:
046-004817-00) for detail.
12.2 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 menu.
2. From the bottom of the ECG menu, select 12-Lead.
You can also enter the 12-Lead screen by following this procedure:
■Select the Screen Setup quick key → select ECG 12-Lead.
■Select Main Menu quick key → from the Display column select Choose Screen → select ECG 12-Lead.
12.3 Initiating Resting 12-Lead ECG Analysis
Before 12-lead ECG interpretation, 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 left bottom of the 12-Lead screen.
12.4 Changing 12-Lead ECG Analysis Settings
On the ECG 12-Lead screen, you can set the high frequency filter, baseline drift removal (BDR) switch, and the
waveform layout.
12.4.1 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 menu.
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 that exceeds the set frequency is filtered out. For
example, if you set High Freq Cut-off to 35 Hz, only signal at 35 Hz or less displays. Signal exceeding 35 Hz is
attenuated.
