ECG Electrode Placement
Before applying ECG electrodes, be sure to
• Remove all clothing covering the patient’s chest.
• Clip or shave any excessive hair to ensure proper adhesion of the electrodes.
• Use alcohol to wash away any oil or dirt at the electrode site.
• Dry any moisture at the electrode site.
Some skin abrasion is necessary to remove the top layer of dead skin cells and expose moist
living cells for better electrical contact. Proper skin preparation reduces baseline wander and
noise and provides a noise-free signal more quickly after electrode application.
Place ECG electrodes on the patient’s chest as shown in Table 5-1.
