Chapter 18: Setting up to acquire physiological data
How ECG triggering works
ECG triggering acquires one single frame of image data during each cardiac cycle,
at precisely the same time point after the R wave peak, as shown in the following
illustration.
Before you begin
Your animal must be connected to the Advanced Physiological Monitoring
Unit.
IMPORTANT: You can only activate and control ECG triggering while you are acquiring
data. You cannot access these options when you review an image.
f To set the ECG triggering:
1. Begin acquiring data and then press.
2. Press
Physio Settings
.
The left panel displays the physiological display setting sections.
3. In the Physiological Display section, select the View Physiology check box
and then select only the ECG check box. This displays only the ECG
waveform in the physiological trace window, which makes it easier to work
with.
4. In the Physiological Range section, adjust the ECG slider so that the trace line
is tall enough to clearly define the peak of the R wave.
5. In the ECG Trigger section:
