Connection of the Chest Electrodes

Before connecting electrodes:
1- Prepare the patient's skin.
 The skin is a poor conductor of electricity; therefore preparation of the patient's skin is
important to facilitate good electrode contact to skin.
 Shave hair from sites, if necessary.
 Wash sites thoroughly with soap and water.
2- Apply some gel on the skin of these sites.
3- Press the suction bulb and place the chest electrode on proper site and then release.
The chest electrodes of 12-lead ECG should be placed in the following sites:
● C1 (V1): Fourth intercostal space at the right margin of the sternum
● C2 (V2): Fourth intercostal space at the left margin of the sternum
● C3 (V3): Midway between V2 and V4
● C4 (V4): Fifth intercostal space at the left midclavicular line
● C5 (V5): Left anterior axillary line at the horizontal level of V4
● C6 (V6): Left mid-axillary line at the horizontal level of V4
