5-Leadwire Electrode Placement
Following is an electrode configuration when using 5 leadwires:

RA placement: directly below the clavicle and near the right shoulder.

LA placement: directly below the clavicle and near the left shoulder.

RL placement: on the right lower abdomen.

LL placement: on the left lower abdomen.

V placement: on the chest.
The chest (V) electrode can be placed on one of the following positions:

V1 placement: on the fourth intercostal space at the right sternal border.

V2 placement: on the fourth intercostal space at the left sternal border.

V3 placement: midway between the V2 and V4 electrode positions.

V4 placement: on the fifth intercostal space at the left midclavicular line.

V5 placement: on the left anterior axillary line, horizontal with the V4 electrode
position.

V6 placement: on the left midaxillary line, horizontal with the V4 electrode position.

V3R-V6R placement: on the right side of the chest in positions corresponding to those on the left.

VE placement: over the xiphoid process.

V7 placement: on posterior chest at the left posterior axillary line in the fifth intercostal space.

V7R placement: on posterior chest at the right posterior axillary line in the
fifth intercostal space.
12-Leadwire Electrode Placement
12-lead ECG uses 10 electrodes, which are placed on the patient’s four limbs
and chest. The limb electrodes should be placed on the soft skin and the chest
electrodes placed according to the physician’s preference.
Lead 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.
