Diagn (diagnostic) filter is used if more accurate information of the waveform is needed (for
example, of the P wave or AV block). The diagnostic filter is more susceptible to both high
frequencies and baseline wander than the monitor filter.
Pacemaker Selects how to display the pacing spike of cardiac pacemaker. The selections are:
Hide = The pacing spike is filtered away from ECG data.
Show = The pacing spike is filtered away from ECG data but the spike is displayed as a
constant height marker.
Sensit = This selection uses a more sensitive pacemaker detection. Pacing spike is displayed on
ECG.
Grid Selects the ECG gridlines to be displayed or not. If you select ON, you can view the ECG
waveforms over gridlines.
5-lead cable Selects five or three electrodes.
V Lead Selects the label for V lead according to the placement of the 5th electrode (see “Placing the
electrodes” on page 11-3).
NOTE: Selectable with the 5 lead trunk cable only.
Selecting a lead
The following lead selections are possible:
− with 3 leadwire set: I, II or III
− with 5 leadwire set: I, II, III, aVL, aVF, aVR or V
− For channels ECG2 and ECG3, also a cascaded lead selection (Casc.) is available.
To select the ECG1 lead:
• Press the ECG key and select ECG1 Lead.
You can select all leads (ECG1, ECG2 and ECG3) in the ECG menu.
The label of the lead is displayed in the ECG field.
Selecting user leads
1. Press the ECG key.
2. Select a lead for ECG1 -3 Lead.
With 3-lead ECG, you can select only one user lead (ECG1 Lead). With 5-lead ECG, you can
select three user leads.
