One- or Two-Channel Signal Processing
The monitor can process one or two ECG leads. If you select two-
channel signal processing, ECG and arrhythmia monitoring is
less vulnerable to artifact, because the monitor can assign a
greater weight to the “cleaner” channel or even exclude a channel
from signal processing altogether, if it exceeds a certain level of
artifact. In this case, ECG monitoring continues without interrup-
tion, unless both channels start showing excessive artifact.
The monitor processes the two leads displayed in the top two
waveform channels. If no lead or only one lead is currently dis-
played in these channels, the monitor uses the last leads previ-
ously displayed there.
NOTE: When you call up the second page of the HR Setup menu
by clicking on
More... (see below), the two ECG leads available for
signal processing appear to the right of the menu. To change these
leads, exit the HR Setup menu, click on waveform channel 1 or 2,
and select a different ECG lead for display.
