•
The ECG preamplifier is used for acquiring an ECG signal to be displayed with the
ultrasound image. The ECG preamplifier must not be used for ECG diagnostics. It is not
intended for use as a cardiac monitor.
•
The ECG preamplifier is connected to a connector on the rear panel of Voluson™
SWIFT / Voluson SWIFT+.
12.5.1 Information for safe use of ECG
•
The simultaneous use of stimulation current devices can influence the ECG signal.
•
If several instruments are simultaneously used on the patient, all instruments must be
connected to an appropriate potential equilibrium (avoidance of lead currents).
•
The ECG provided for use with this system is defibrillation-proof.
•
When using a defibrillator while having the ECG connected, also always refer to the
defibrillator's Instructions for Use .
12.5.2 Handling
•
Position, speed and amplitude of the displayed ECG strip can be altered in the ECG
menu of the ultrasound machine.
•
The patient cable shall always be connected to the ECG preamplifier.
•
With the patient cable belonging to the ECG preamplifier only electrodes for push-button
connection can be used. Depending on requirements, commercially available extremity
clamp electrodes together with conductive gel or commercially available pre-jelled
adhesive electrodes can be used, preferably the latter should be used.
•
With standard setting of the electrodes (red = right arm, yellow = left arm, black = left leg)
lead I is displayed. Other electrode arrangements may be necessary (lead II, III), if
amplitude supplied by lead I is too small.
1.
Adjust the transmission gain of the ECG preamplifier signal (0, 1, 2, 3).
2.
Select ECG velocity (0, 1, 2, 3).
3.
Set the vertical position on the monitor.
4.
Adjust ECG amplitude ( 0 to 100 in 10 steps).
5.
Return to the main menu. The ECG function remains active.
6.
Freeze the image. The most recent information is always on the right edge of the image.
When moving the trackball a indicator (small vertical line) is inserted on the ECG curve and
indicates the temporal position of the 2D image in relation to the recorded ECG line. In this
manner e.g., diastolic or systolic phase of the 2D mode image can be set (without ECG
trigger).
