Preparing the Patient
4. Apply electrodes to the prepared sites.
Electrodes should be placed only by a physician or ECG technician.
WARNING:
SHOCK HAZARD — Touching the conductive elements cancels the protection
provided by the isolated signal input.
Ensure that conductive parts of the electrodes or lead wires do not come in
contact with other conductive parts.
5. Look at the lead-check screen for indication of lead problems.
NOTE:
Use only electrodes and contact agents recommended by GE Healthcare.
The signal quality on the lead-check screen is not indicated until the RA/R
and RL/N electrodes are applied. If RA/R becomes disconnected, the system
reports that all electrodes are off the patient.
Electrode Placement
This section describes various methods for placing electrodes for both resting and
exercise ECGs.
NOTE:
Some of the procedures for placing electrodes may not apply in all cases,
depending on the system and options purchased.
CAUTION:
DELAYED DIAGNOSIS — Improper connection of the leadwires will cause
inaccuracies in the ECG.
Ensure the leadwires are connected properly. Trace each leadwire from its
acquisition module label to its colored connector and then to its electrode to
ensure that it is matched to the correct label leadwire connection location.
Resting ECG Placement
The following methods are applicable for resting ECGs.
