11.4.7 Enabling Pacer Rejection
The pace pulse rejection function is disabled by default. To enable this function, follow this procedure:
1. Select the ECG numeric area or waveform area to enter the ECG menu.
2. Select the Pacer tab.
3. Switch on Pacer Reject.
• When pace pulses are detected, the pace pulse marks “|” are shown on the ECG waveforms. Pacer
Rejection setting has no impact on the display of pace pulse marks “|”.
• You can switch on pacer rejection only when Paced is set to Yes. If Paced is set to no, the setting of
Pacer Reject is disabled.
11.5 Using 6-lead Placement to Derive 12-lead ECG (D12L)
The monitor supports using the 6-lead placement to derive 12-lead ECG. This function is called D12L. When
D12L is enabled, the monitor can derive four additional chest leads according to directly acquired ECG signals.
D12L provides a non-diagnostic 12-lead view, including ECG waveforms and ST/QT measurements. D12L is
intended for adult patients only.
The available Va and Vb combinations supporting D12L are:
■ V1 and V3, V1 and V4, V1 and V5
■ V2 and V4, V2 and V5
■ V3 and V5, V3 and V6
D12L is disabled by default. To enable D12L, follow this procedure:
1. Select the ECG numeric area or waveform area to enter the ECG menu.
2. Select the Setup tab.
3. Select the positions of Va and Vb. You shall use an available Va and Vb combination.
4. Switch on D12L.
• D12L is not intended for pediatric and neonatal patients.
• The positions of Va and Vb shall be consistent with the settings of Va and Vb. Otherwise D12L does
not work properly.
• The derived 12-lead ECGs and their measurements are approximations to conventional 12-lead
ECGs. The derived leads cannot be used for heart rate calculation and arrhythmia analysis.
• The derived 12-lead ECGs should not be used for diagnostic interpretations.
• You shall use the available Va and Vb combination supporting D12L. I f you choose other
combinations, D12L does not work and the message “D12L not available” is prompted.
11.6 Changing ECG Settings
11.6.1 Choosing an ECG Screen
When monitoring ECG, you can choose the screen as desired.
■ For 3-lead ECG monitoring, only normal screen is available.
■ For 5-lead ECG monitoring, besides the normal screen, you can also choose 7-lead full screen or 7-lead half
screen.
