10.4.4 ECG Electrode Placements
In this section, electrode placement is illustrated using the AHA naming convention.
10.4.4.1 3-leadwire Electrode Placement
The following is an electrode configuration when a 3-leadwire cable is used:
■
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.
10.4.4.2 5-leadwire Electrode Placement
The following is an electrode configuration when when 5-leadwires is used:
■
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.
10.4.4.3 6-leadwire Electrode Placement
For 6-leadwire placement, you can use the position for the 5 -leadwire placement but with two chest leads. The
two chest leads (Va and Vb) can be positioned at any two of the V1 to V6 positions. For more information, see
10.4.4.4 Chest Electrode Placement . The Va and Vb lead positions are configurable. For more information, see
10.6.4.4 Changing Va and Vb Labels .
When 6-lead placement is used to derive 12-lead ECG, Va and Vb shall use any of the following combinations.
■ V1 and V3, V1 and V4, V1 and V5
■ V2 and V4, V2 and V5
■ V3 and V5, V3 and V6
10.4.4.4 Chest Electrode Placement
The chest electrode can be placed at 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.
