Limb electrodes should be installed on the soft skin of hands and legs. Clean the skin where
electrodes will be installed with medical alcohol; Apply a small amount of electrode gel on
the skin.
The connection is shown in the following figure:
The location for Limb electrodes are:
R (RA) connect right hand
L (LA) connect left hand
RF (RL) connect right leg
F (LL) connect left leg
3.2.2 Chest electrodes connection
Clean the skin where electrodes will be
connected with alcohol; Apply about 25mm
diameter electrode gel on the skin where the
electrodes contacted; Apply a small amount of
electrode gel on the edge of the sucker ball of the chest electrodes; Press the suction ball of
the chest electrodes; attach them to C1-C6. The connection is shown in the following
figure
C1 (V1): Fourth inter-costal space at right border of the sternum.
C2 (V2): Fourth inter-costal space at left border of the sternum.
C3 (V3): Midway between locations C2 and C4.
C4 (V4): Mid-clavicular line in the fifth inter-costal space.
C5 (V5): Left anterior axillary line on the same horizontal level as V4.
C6 (V6): Left mid-axillary line on the same horizontal level as V4.
Electrode gel coating should to be separated from each other. Chest electrodes should not
touch with each other to avoid short circuit. If no electrode gel is available, apply a small
amount of 75% alcohol instead .Place the electrodes right away to make sure it is
adequately wet at the contact area. Do not use physiological saline to replace electrode gel.
Otherwise, it will cause electrode corrosion.
