5.4.2.2 ECG Electrode Placements
3-Lead Placement
The following is a typical AHA electrode placement for a 3-lead ECG set:
■ RA placement: directly below the clavicle and near the right shoulder.
■ LA placement: directly below the clavicle and near the left shoulder.
■ LL placement: on the left lower abdomen.
5-Lead Placement
The following is a typical AHA electrode placement for a 5-lead ECG
set:
■
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 left posterior axillary line in the fifth intercostal space.
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.
