Acclarix LX9 Series Diagnostic Ultrasound System User Manual
5.12 ECG
Table 5-12 Elastography Touch Screen Controls
The ultrasound system can be configured with an optional ECG module. The ECG module obtains
ECG signals via ECG patient cable to display ECG waveform synchronously with the ultrasound
image. The ECG signals can be used as time reference in cardiac exam for marking the systolic and
end diastolic moments.
1. The ECG waveforms displayed on the main screen are not intended for ECG diagnosis and
monitoring.
2. The ECG module and electrodes are not intended for intra-cardiac use or direct cardiac contact.
3. Do not use the ECG function on the patient with pacemaker.
4. Only the ECG module, patient cable and electrodes supplied by EDAN can be used.
5. Only authorized service personnel can service the ECG module.
6. The conductive parts of electrodes and associated connectors, including the neutral electrode,
should not contact any other conductive parts including earth.
7. The electrodes must be removed from the patient before a high-frequency surgical equipment is
used on the patient.
8. The quality of the ECG waveform depends on the stability and conductivity of the electrodes
because patient's movements can cause artifacts.
9. Only the ECG applied part is defibrillation-proof. Please remove transducer and other
accessories from patient before defibrillation. Always refer to the defibrillator's user manual when
performing defibrillation.
10. After defibrillation, the ECG waveform recovers within 10 seconds if the correct electrodes are
used and applied according to the manufacturer's instructions.
11. Always do the follows prior to operation:
Check the patient cable for visible evidence of any damage. If any damage is found, a new
patient cable should be used.
Connect the electrodes to patient correctly following the manufacturer's instruction. If a ECG lead
is off, the ultrasound system will display " ECG Lead Off " message..
12. The disposable electrodes can only be used for one time. Do not use the electrodes passing its
expiry date.
13. The disposable electrodes should be disposed of according to the local regulations.
14. Regularly check, clean and maintain the patient cable and electrodes following the
manufacturer's instruction.
