Physio controls
Physio assignable controls
Common controls
Horizontal sweep
Adjust the refresh rate of the physiological trace. This control is 
active only in 2D and color modes. The sweep speed of the 
physio traces in M-Mode and Doppler is identical to the M-
Mode or Doppler horizontal sweep adjusted by the user.
Gain
Enables the user to change the amplitude of the physiological 
trace displayed on the screen.
Position
Enables the user to move the physiological trace on the screen.
ECG specific controls
ECG Lead
Enables the user to choose the lead from which the ECG is 
recorded:
•  Lead I: ECG recorded between right and left arm.
•  Lead II: ECG recorded between right arm and left leg.
•  Lead III: ECG recorded between left arm and left leg.
ECG Trig
Enables intermittent imaging based on the ECG.
Timer Trig
Enables intermittent imaging based on a timer.
ECG
Turns the ECG trace on and off.
Beep
Turns beep sound on and off.
Press MORE to ac-
cess to the Phono 
and Respiration 
controls.Phono specific controls
Phono
Turns the phono trace on and off.

Phono filter
Select a phono filter to apply from a pop-up menu.
Respiration specific controls
Respiration
Turns the respiration trace on and off.
AUX specific controls
AUX1
Turns the AUX1 physiological trace on and off.
AUX2/Press
Turns the AUX2 physiological trace on and off.
Physio Soft menu controls
ECG Trig 1
Specifies the delay (ms) from R-wave to triggered frame.
ECG Trig 2
Specifies the delay (ms) from R-wave to second frame. Trig 2 
must be greater than Trig 1 for dual triggering to be active.
ECG Trig interval
Number of heart cycles between triggered images.
Timer Delay
Controls time between triggers when timer triggering is turned 
on.
Displaying the physiological traces
Display of the ECG
To turn the ECG 
display off, press 
PHYSIO and press 
the assignable 
ECG.
Cardiac applications
The ECG is turned on by default in all cardiac applications.
Other applications

AUX 2 to display the pulse pressure 
trace.
Adjusting the display of physiological 
traces
Adjusting the trace sweep speed (ECG, phono 
and respiration)
1. Press PHYSIO on the control panel.
2. Turn the assignable rotary Horizontal Sweep to change 
the sweep speed.
Adjusting the trace amplitude (ECG, phono, 
respiration and pulse pressure)
The ECG signals 
amplitude may vary 
between patients 
due to different skin 
moisture and other 
physiological pa-
rameters.1. Press PHYSIO on the control panel.
2. Press 
MORE to select the actual assignable set.
3. Turn the assignable rotary Gain to adjust the amplitude of 
the trace.

3. Turn the assignable rotary POSITION to move the trace 
vertically.
ECG Trigging
1. Press PHYSIO on the control panel to access to the ECG 
controls. 
2. Press the assignable 
ECG TRIG.
3. Using the 4-way Rocker, adjust Tri g  1 to position the first 
trig on the ECG (delay in ms from R-wave to triggered 
frame).
For dual triggering 
Trig 2 must be grat-
er than Trig 1.4. Using the 4-way Rocker, highlight Tri g  2 if dual triggering 
is to be used.
5. Adjust Tri g  2 to position the second trig on the ECG.
6. Using the 4-way Rocker, highlight Trig Interval.
7. Using the 4-way Rocker, adjust the number of heart cycles 
between triggered frame acquisition.
