8.3.3 ECG Lead Placements
The electrode placement illustrations in this chapter adopt the AHA standard.
3-Leadwire Electrode Placement
Following is an electrode configuration when using 3 leadwires:
 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-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.
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.
