11.4.4.3 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
11.4.4.4Chest Electrode Placement. The Va and Vb lead positions are configurable. For more information, see
11.6.4.4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.
â– V1 and V3, V1 and V4, V1 and V5
â– V2 and V4, V2 and V5
â– V3 and V5, V3 and V6
11.4.4.4 Chest Electrode Placement
The chest electrode can be placed at the following positions:
â– V1 placement: on the fourth intercostal space at the right sternal border.
â– V2 placement: on the fourth intercostal space at the left sternal border.
â– V3 placement: midway between the V2 and V4 electrode positions.
â– V4 placement: on the fifth intercostal space at the left midclavicular line.
â– V5 placement: on the left anterior axillary line, horizontal with the V4
electrode position.
â– V6 placement: on the left midaxillary line, horizontal with the V4
electrode position.
â– V3R-V6R placement: on the right side of the chest in positions
corresponding to those on the left.
â– VE placement: over the xiphoid process.
â– V7 placement: on posterior chest at the left posterior axillary line in the
fifth intercostal space.
â– V7R placement: on posterior chest at the right posterior axillary line in
the fifth intercostal space.
• For the 5-leadwire and 6-leadwire placement, place the precordial electrode according to the
physician's preference.
11.4.4.5 10-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 limb extremities and
the chest electrodes placed according to the physician’s preference. The
picture at the right shows the conventional 10-leadwire electrode placement.
