Choosing EASI or Standard Lead Placement
You must enable either standard lead placement or EASI lead placement.
♦ In the Setup ECG menu, select Lead Placement and then Standard or EASI.
EASI is shown beside the 1mV calibration bar on the ECG wave on the display, and EASI is marked
on any recorder strips and printouts.
See the section on EASI ECG Lead Placement for electrode placement diagrams.
About ECG Leads
To make it possible to compare measured ECG signals, the electrodes (or lead sets) are placed in
standardized positions, forming so-called “leads”. To obtain ECG signals optimized for use in
diagnosis and patient management in different care environments, different lead sets in varying lead
placements can be used. You can use either standard lead placements or EASI lead placements with this
monitor.
When placing electrodes, choose a flat, non-muscular site where the signal will not be interfered with
by either movement or bones. Correct lead placement is always important for accurate diagnosis.
Especially in the precordial leads, which are close to the heart, QRS morphology can be greatly altered
if an electrode is moved away from its correct location.
ECG Leads Monitored
Changing Lead Sets
To change the ECG lead set,
• When adding leads: place the additional electrodes as required - the monitor automatically
recognizes the new lead placement.
• When removing leads: there are two possibilities - removing the complete chest leads block or
removing individual leads. If you unplug the chest lead block from the trunk cable connector, the
monitor will automatically recognize the new lead placement. Remove individual leads by removing
the electrodes. The monitor will issue a Lead Off INOP message; select New Lead Setup in
the Setup ECG menu and the INOP message will disappear.
If you are using these leads are available: Resp is measured
