NOTE:
1 The 12-lead analysis results are for reference only and the analysis significance must
be determined by the physician.
2 If the ECG signal is too weak, the 12-lead analysis results might be affected.
3 SEMIP algorithm is a 12-lead ECG automatic measurement and analysis algorithm.
Regarding to the standards' instructions for ECG measurement and analysis of the
monitor, please refer to Smart ECG Measurement and Interpretation Programs User
Manual_EDAN2.
4 For 12-lead analysis, the gain selection contains: 1.25 mm/mV (×0.125), 2.5 mm/mV
(×0.25), 5 mm/mV (×0.5), 10 mm/mV (×1), AUTO gain.
9.7.1 Activating 6/10 Electrodes ECG Monitoring
Select Menu > Maintenance > User Maintain > Other Setups > Activate 6/10 Electrodes in
order to get the SN number which is supposed to be supplied to EDAN for a corresponding
password. Enter the password on the above-mentioned interface and restart the monitor, and the
6/10 Electrodes ECG monitoring function will be activated.
NOTE:
If the 6/10 Electrodes ECG monitoring fails to be activated, users can reenter the
password and try to activate this function again.
9.7.2 Analysis Function
If your monitor is configured with the 12-lead ECG monitoring function, the monitor can perform
automatic analysis function. To perform 12-lead analysis:
1. In the ECG Setup menu, set Electrode Type to 10 Electrodes and set Screen Layout to 12
Leads.
2. Select the shortcut key on the screen directly.
3. The analysis results will be provided in the Analysis Review window after approximately 10
seconds.
The measurement function provides the automatic measurement of the common parameters, such
as heart rate, PR interval, QRS duration, QT/QTC interval, P/QRS/T axis, RV5/SV1 amplitude
and RV5+SV1 amplitude. The interpretation function provides the automatic analysis of
hundreds of abnormal cases, such as arrhythmia, AV block, IVCD (Intraventricular Conduction
Block), myocardial infarction, ventricular hypertrophy and atrial enlargement, ST-T abnormality
and electrical axis deviation.
9.7.3 Waveform Durations and Isoelectric Segments
Between the global onset and offset of the QRS-complex, signal parts with a duration of more
than 6 ms and amplitude not exceeding 20 μV should be defined as isoelectric segments.
