As the following figure shows, the positions of chest electrodes on the body surface are
C1: Fourth intercostal space at the right border of the sternum
C2: Fourth intercostal space at the left border of the sternum
C3: Fifth rib between C2 and C4
C4: Fifth intercostal space on the left midclavicular line
C5: Left anterior axillary line at the horizontal level of C4
C6: Left midaxillary line at the horizontal level of C4
The quality of ECG waveform will be affected by the contact resistance between the patient
and the electrode. In order to get a high-quality ECG, the skin-electrode resistance must be
minimized when you attach electrodes to patients.
Chest Electrode Connection:
1)
Ensure that the electrodes are clean;
2)
Align all lead wires of the patient cable to avoid twisting, and connect the lead wires to
the corresponding electrodes according to the colors and the identifiers;
3)
Clean the electrode area on the chest surface with alcohol;
4)
Daub the round area of 25mm in diameter on each electrode site with gel evenly;
5)
Place a small amount of gel on the brim of the chest electrode’s metal cup;
6)
Place the electrode on the chest electrode site and squeeze the suction bulb. Unclench it
and the electrode is adsorbed on the chest;
7)
Attach all chest electrodes in the same way.
