ECG tests
Attaching the leads to the patient
Proper lead attachment is important for a successful ECG. The most common ECG
problems are caused by poor electrode contact and loose leads. Follow your local
procedures for attaching the leads to the patient. Here are some common guidelines.
WARNING Electrodes can cause allergic reactions. To avoid this, follow
the electrode manufacturer’s directions.
To attach the leads to the patient
1. Prepare the patient.
• Describe the procedure. Explain the importance of holding still during the test.
(Movement can create artifact.)
• Verify that the patient is comfortable, warm, and relaxed. (Shivering can create
artifact.)
• Put the patient in a reclining position with the head slightly higher than the heart
and legs (the semi-Fowler’s position).
2. Select the electrode locations. (See the “Electrode locations” chart.)
• Look for flat areas.
• Avoid fatty areas, bony areas, and major muscles.
3. Prepare the electrode locations.
• Shave or clip the hair.
• Thoroughly clean the skin, and lightly rub it dry. You may use soap and water,
isopropyl alcohol, or skin preparation pads.
4. Attach the lead wires to the electrodes.
5. Apply the electrodes to the patient.
