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- Place the chest electrode on proper site and press its suction bulb to attach it to the skin.
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 midaxillary line at the horizontal level of V4
