Chapter 10 Electrode Installation
You'd better install the chest electrode firstly, then Limb electrode.
10.1 Chest electrode, as shown in figure 10-1:
Figure 10-1: chest electrode locations
The position of installing chest electrodes are as following:
V1: Fourth inter-costal space at right border of sternum.
V2: Fourth inter-costal space at left border of sternum..
V3: Midway between V2 and V4.
V4: Fifth inter-costal space at left mid-clavicular line.
V5: Left anterior axillary line at the horizontal lever of V4.
V6: Left mid-axillary line at the horizontal lever of V4.
Cleaning the chest skin with alcohol, then put the gel in the diameter about 25mm and the edge
of the chest electrodes ,press the ball of the chest electrodes, the chest electrodes will be
attracted in the position of V1-V6.
Attention: The chest electrodes should be separated from gel coats, this operation can avoid
short circuit.
10.2 Limb electrode
Figure 10-2:Limb electrode locations
Clean all the limb electrodes and the positions around to which limb electrodes are to be
attached with alcohol before applying ECG cream to them, then firmly attach the electrodes to
the positions.
Attention: the fix knob should be screwed down tightly after lead connected with main
