6.4 Electrode installation
Proper installation of the electrodes is an important part of accurately recording the
electrocardiogram. Make sure the electrodes are in good contact. Old and new electrodes or
reusable electrodes and disposable electrodes cannot be used at the same time. If different types
of electrodes are used together, it will seriously affect the ECG recording. The electrode or lead
plug must not touch other object surfaces or conductors, such as metal beds. Please replace them
all when updating the electrodes.
6.4.1 Chest electrodes
As shown in Figure 6-3:
Figure 6-3 Installation of chest electrode
The chest electrodes should be installed to the following parts:
C1
（ Vl ） : the fourth intercostal space at the right sternal margin
C2 （ V2 ） : the fourth intercostal space at the left sternal margin
C3 （ V3 ） : between C2 and C4
C4 （ V4 ） : the intersection between midclavicular line and the fifth intercostal space
C5 （ V5 ） : left anterior axillary line on the same plane as C4
C6 （ V6 ） : left midaxillary line on the same plane as C4
Clean the chest skin where the electrodes to be installed with alcohol, and apply some
conductive pastes to these skin (about 25 mm-diameter range) and the edge of the chest electrode
suction cup. Squeeze the suction ball to install the chest electrode at the positions of Cl-C6.
Note: The conductive paste coating should be separated from each other, and the chest
electrodes should not touch each other to avoid short circuit.
Note: Please use qualified conductive paste to avoid damaging the skin.
6.4.2 Limb electrodes
The limb electrodes should be placed on the soft skin of both hands and feet. Before
connecting, clean the skin of the electrode installation area with alcohol, and then apply a small
amount of conductive paste on the cleaned skin. The electrode connection of the limbs is shown
in Figure 6-4.
