How do you apply Holter monitor leads?
Place the left arm (LA) electrode near the left shoulder, close to the junction of the left arm and torso.

Where are the leads placed for a Holter monitor?
The leads connect to electrodes that are placed on the skin of your chest with a glue-like gel. The metal electrodes conduct your heart’s activity through the wires and into the Holter monitor, where it’s recorded. You wear a small pouch around your neck that holds the monitor itself.
What can you not do while wearing a Holter monitor?
Certain devices can interrupt the signal from the electrodes and distort your Holter monitor test results. Stay away from microwaves, electric blankets, electric toothbrushes, electric razors, and metal detectors. If you absolutely need to go through a metal detector, then walk through it at a normal pace.

At what point should you attach the electrodes to the patient?
At the horizontal level of V4, at the anterior axillary. At the horizontal level of V4, at the midaxillary line. Attach the electrodes and lead wires: After the locations are properly prepared; apply fresh electrodes to the patient.
Where do chest leads go?
12-lead Precordial lead placement
- V1: 4th intercostal space (ICS), RIGHT margin of the sternum.
- V2: 4th ICS along the LEFT margin of the sternum.
- V4: 5th ICS, mid-clavicular line.
- V3: midway between V2 and V4.
- V5: 5th ICS, anterior axillary line (same level as V4)
- V6: 5th ICS, mid-axillary line (same level as V4)
Which of the following should a patient do when wearing a Holter monitor?
Do your usual activities while you wear the monitor with these exceptions: Don’t bathe, shower or swim while wearing the monitor. Don’t have X-rays while wearing the monitor. Stay away from high-voltage areas, metal detectors or large magnets.
