EKG Lead Placement
Placement of
the limb leads on a three or five lead system.
A five lead system will use all the leads shown below, whereas a three
lead system uses only the black, white and red leads. Two lead telemetry
systems use the black and red leads, but placement may change depending
on what EKG lead (view) is required.
The
black and white leads are placed on the shoulder area where the
shoulder connects to the torso. The green and red leads are placed
on the lowest rib on both sides of the torso, and the brown lead
is placed at the 4th intercostal space, just to the right of the
sternum.
Addition
of the Chest Leads
To
make up the full 12-lead system, additional leads are placed across
the chest wall. These leads are called V1 to V6.
V1
- 4th intercostal space, just to the right of the sternum.
V2 - 4th intercostal space, just to the left of the sternum.
V3 – Midway between V2 and V4
V4 - Mid clavicular line, 5th intercostal space.
V5 – Anterior axillary line, between V4 & V6
V6 - Mid axillary line, horizontal with V4.
