Chest Electrode Placement

For accurate chest electrode placement and measurement, it is important to
locate the fourth intercostal space.
 To locate the fourth intercostal space:
1
Locate the second intercostal space by first palpating the Angle of Lewis
(the little bony protuberance where the body of the sternum joins the
manubrium). This rise in the sternum is where the second rib is
attached, and the space below this is the second intercostal space.
2
Palpate and count down the chest until you locate the fourth intercostal
space.
Chest Electrode Placement
V1 on the fourth intercostal space at the right
sternal border
V2 on the fourth intercostal space at the left
sternal border
V3 midway between the V2 and V4 electrode
positions
V4 on the fifth intercostal space at the left
midclavicular line
V5 on the left anterior axillary line, horizontal
with the V4 electrode position
V6 on the left midaxillary line, horizontal with
the V4 electrode position
V3R-V6R on the right side of the chest in
positions corresponding to those on the left
VE over the xiphoid process
V7 on posterior chest at the left posterior
axillary line in the fifth intercostal space
V7R on posterior chest at the right posterior
axillary line in the fifth intercostal space
