Chapter10 Electrode Placement
It is better to attach chest electrodes first, then the limb electrodes.
10.1 Chest Electrode Placement( See the figure below)
Attach the chest electrodes to the locations 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.
Clean the skin where chest electrodes are to be attached with alcohol, then apply ECG cream to
here around 25mm in diameter and to the edge of chest electrodes, then press and attach the
electrodes to the positions from V1-V6.
Note:
Keep in mind that the electrodes’ coming into contact with each other or cream’s
overlap from one position to another is not allowed to avoid short circuit.
10.2 Limb Electrode Attachment
Electrodes should be placed on the soft skin of hands and feet. Clean all the limb electrodes and
the positions where limb electrodes are to be attached with alcohol before applying ECG cream to
them, then firmly attach the electrodes to the positions.
Note: Screw tightly the knob of ECG cable's plug after it is inserted to the ECG connector.
