Selecting Positions of Va and Vb Chest Leads (for 6-lead placement)

– Diag: Use when diagnostic quality is required. The unfiltered ECG wave is displayed so that
changes such as R-wave notching or discrete elevation or depression of the ST segments are
The setting Diag selects the highest available ECG bandwidth which is 0.05 to 150 Hz for the
Adult, Pedi and Neo patient category. The term "diagnostic" relates only to the ECG bandwidth
requirements for diagnostic electrocardiographic devices as outlined in the ANSI/AAMI standard
When you are using a telemetry transmitter connected via short range radio to the monitor, the
upper bandwidth for all filter settings is limited to 40 Hz.
Selecting Positions of Va and Vb Chest Leads (for 6-
lead placement)
The two chest leads for the 6-lead placement can be positioned at any two of the V1 to V6 positions.
Select the positions you have used in the Setup ECG menu, so that the chest leads will be correctly
In the Setup ECG menu, select Va Lead.
Select the position used from the list.
Select Vb Lead and select the position used from the list

Choosing EASI or Standard Lead Placement

You must enable either standard lead placement or EASI lead placement.
In the Setup ECG menu, select 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 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
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.
