10�6 Using ECG
Using an optional ECG module (Type BF), 3-channel ECG signals are provided in cardiac applications.
During a cardiac application, you can configure the ECG-control so that the ECG trace is displayed at the bottom of
the screen. The ECG module provided by this ultrasound system is for collecting and displaying 3-lead ECG trace.
The ECG cable includes three color-coded ECG electrode connectors, i.e., LL (left leg, red), LA (left arm, black),
and RA (right arm, white). Among them, LA is the reference cable, receiving the signal from the ECG module and
providing the bias voltage. LL and RA receive signals from the patient body and connect to the different output
terminals of ECG isolation amplifier.
!
● This ECG module is not suitable for intracardiac use or direct cardiac contact.
● This ECG module provides 3-channel ECG signals and cannot be used for diagnosis and monitoring.
● To avoid electrical shock, ensure the ECG cable is intact and correctly connected.
●
Conductive parts of electrodes and connectors for ECG should not come into contact with other conductive
parts including earth/grounding.
● Power off the ultrasound system if the patient is found to use a pacemaker or implantable cardioverter-
defibrillators, because the ultrasound system may interfere with these devices.
