11 - 2 BeneVision N22/N19 Patient Monitor Operator’s Manual
11.1 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.
11.1.1 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.
11.2 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.
11.3 Changing 12-Lead ECG Analysis Settings
11.3.1 Changing the Filter Mode for 12-Lead ECG Analysis
When you enter the 12-lead screen, the filter mode automatically switches to Diagnosis. In the presence of too
much myoelectric interference, you need to set the filter mode to
ST. To do so, 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
Filter to ST.
11.3.2 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.
