8-16 DELTA/DELTA XL/KAPPA VF8
8 ECG
AND HEART RATE
ECG Signal Processing and Display
The monitor identifies QRS complexes with amplitudes between 0.2 and 5.0 mV and
a QRS width of 70 to 120 ms for adults (or 40 to 100 ms for neonates; see note on
page 8). It calculates heart rates within a range of 15 to 300 beats per minute, using the
R-R intervals of the last 10 seconds and disregarding the two longest and two shortest
R-R intervals. It averages the remaining intervals, and displays the result as the
current heart rate in the HR parameter box on the main screen.
During dual-channel processing, the monitor assigns a weight to each channel
depending on its level of artifact (the cleaner channel receives a greater weight). When
the noise in one channel exceeds a certain level, the channel is excluded from the
composite signal, and the monitor effectively shifts to single-channel processing. The
level of artifact on an analyzed channel determines the weight that channel receives (a
cleaner channel receives a greater weight). When the noise in one channel exceeds a
certain level, the channel is excluded from the composite signal, and the monitor
effectively shifts to single-channel processing. If both channels show excessive noise,
the message ECG Artifact appears until at least one channel is sufficiently noise-free.
 During brief artifact, the heart rate is blanked. During extended artifact, the
heart rate value is displayed as * * *.
 When artifact clears, the monitor resumes QRS processing but does not
initiate a relearn.
When you enable arrhythmia monitoring (not available for neonatal patients), the HR
parameter box changes accordingly. If you select
Basic, the four basic arrhythmia
calls ASY, VF, VT, and ARTF are available for display. If you select
Full and you
configure the main screen to display two or more ECG channels, a separate
ARR
parameter box appears below the
HR parameter box (see page 9 for information about
selecting an arrhythmia mode).
