24 Hour Holter Monitoring

A Holter monitor is a small, battery-powered device that measures your heart’s rate (speed) and rhythm. Your doctor may ask you to wear one if they need more information than a standard 30 second ECG provides. 

Holter monitors can help diagnose the cause of palpitations, light headedness or fainting spells. They are also used to help guide the dosing of medications for heart rhythm issues like Atrial Fibrillation or Atrial Flutter

What to expect

A Holter monitor is slightly larger than a deck of playing cards. Several leads, or wires, are attached to the monitor and are connected to electrodes (stickers) that are placed on the skin of your chest. The electrodes capture your heart’s electrical activity which is recorded by the Holter monitor. You wear a small pouch around your neck that holds the monitor itself. 

 

See below for instructions for before your holter appointment. You’re encouraged to participate in your normal activities during the 24-hour Holter test. You’ll be directed to record your activities in a notebook which will help your doctor determine if changes in heart activity are related to your behaviors and movements.

Wearing the Holter monitor itself has no risks involved. However, the tape or adhesives that attach the electrodes to your skin can cause mild skin irritation in some people. Make sure to tell the technician that attaches your monitor if you’re allergic to any tapes or adhesives.

How to prepare for your Holter appointment

  • Please bring a list of all current medications to your holter appointment (your pharmacist can provide you a list to bring to medical appointments)

  • Shower or bathe just prior to your appointment

    • Do NOT apply any lotions, powders or perfumes prior to the appointment​

  • Wear a comfortable two piece outfit that allows easy access to the front of the chest 

    • A button down shirt or zip up shirt is advised​

    • Wear a comfortable bra as it is advised to wear it throughout the 24 hour testing period to avoid accidentally removing or disrupting the monitor

  • Note: it may be necessary to shave areas of chest hair where sensors are attached
