8-4
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.
