Ambulatory Monitor Placement Basics

Set up Holter/event monitors so patients capture good data — placement, skin prep, and instructions.

Beginner~11 min

Learning Objectives

  • 1.Apply an ambulatory monitor with good electrode contact.
  • 2.Instruct patients on wear, symptom logging, and care.
  • 3.Avoid common reasons for poor recordings.

Goal

Holter and event monitors only help if they record clean data over days. Good skin prep and clear patient instructions make or break the study.

Step-by-step

  1. 1.Explain the purpose and how long they’ll wear it.
  2. 2.Prep skin well (clean, dry, clip hair) for lasting adhesion.
  3. 3.Place electrodes/leads per the device instructions; secure cables.
  4. 4.Show how to use the symptom/event button and the diary.
  5. 5.Review do’s and don’ts (showering per device, keep it on).

Patient instructions

  • •Keep the monitor on continuously for the full period.
  • •Press the event button and log the time when symptoms occur.
  • •Note activity with symptoms (e.g., "climbing stairs, dizzy").
  • •Follow device-specific water/shower rules.
  • •Return the monitor and diary as instructed.

What NOT to do independently

  • •Don’t interpret recordings or diagnose; set up and instruct.

Scope note

You apply the device and teach its use; the recording is read by the provider.

Red flags to report immediately

  • •If the patient reports current concerning symptoms (chest pain, fainting) during setup, alert the nurse/provider.

Alert now

Active red-flag symptoms aren’t a "log it on the monitor" situation — escalate.

Documentation tips

  • •Record device type, start time, and that instructions/diary were given.

Checklist

  • Good skin prep and secure placement.
  • Taught event button and diary use.
  • Reviewed wear/shower rules and return.
  • Escalated active red-flag symptoms.
