Electrode Placement for Surgical Patients
The surgical site should be taken into consideration when placing electrodes on a surgical patient, e.g. for open-chest
surgery, the chest electrodes can be placed on the lateral chest or back. To reduce artifacts and interference from
electrosurgical units, you can place the limb electrodes close to the shoulders and lower abdomen and the chest
electrodes on the left side of the mid-chest. Do not place the electrodes on the upper arm. Otherwise, the ECG
waveform will be very small.
WARNING

When using electrosurgical units (ESU), place ECG electrodes between the ESU and its grounding plate to
prevent unwanted burns. Never entangle ESU cable and ECG cable together.

When using electrosurgical units (ESU), never place ECG electrodes near to the grounding plate of the ESU,
as this can cause a lot of interference on the ECG signal.
7.4.2 ECG Monitoring with Pads
1. Prepare the patient’s skin.
2. Apply pads according to the instructions for use indicated on pads package. Use anterior-lateral placement.
3. Connect the pads cable with the equipment if not pre-connected.
Pads placement for Adult Patient
1. Place the RA pad on the patient’s upper right torso, lateral to the sternum and below the clavicle, as shown below.
2. Place the LL pad to the patient’s left nipple in the midaxillary line, with the center of the electrode in the midaxillary
line, if possible. See the figure below.
