14 Directions for Use Welch Allyn Holter System
To Prepare the Patient and Place Electrodes
Help the patient get comfortable. Patient preparation is important for a successful Holter
procedure.
1. Describe the procedure to the patient.
2. Prepare electrode locations. See Figure 4 on page 15 for 5-lead placement, Figure 5
on page 16 for 7-lead placement, Figure 8 on page 18 for 12-lead placement.
3. Shave the area for electrode placement, if necessary.
4. Clean electrode sites with alcohol.
5. Allow electrode site to dry.
6. Attach the electrodes to the lead wires before attaching to patient.
7. Secure each lead wire. Loop each lead wire into a 1- to 2-inch diameter loop, position
it approximately two inches from each sensor site, and tape it to the skin (see
Figure 3 on page 14). This reduces movements that cause signal artifact.

Clinician tasks
Explain to the patient:
• the recording procedure
• how to record information in the patient diary
• how to use the Patient Event Button
• to avoid contact with water
Caution Always ensure that the appropriate electrode placement is employed
for the lead configuration selected.
Caution ECG electrodes can cause skin irritation. Examine the skin for signs of
irritation or inflammation and avoid placement of the electrode in those areas. If
skin irritation occurs during the procedure advise the patient to remove the
electrodes and contact the health service provider as soon as possible.
