Holter and Event Monitors

Both Holter and event monitors are types of ambulatory electrocardiograms that record the electrical activity of your heart while you go about your usual activities. If you experience symptoms, you may be asked to push buttons on the monitor to indicate when and what you felt.

A Holter monitor is a small, wearable device that records your heart rhythm continuously for up to 72 hours.

An event monitor is a wearable device that records your heart continuously for 3-30 days. The recordings are monitored throughout the day by support staff.

With these monitors, your doctor can see your heart rhythm when you go about your normal activities. Abnormal rhythms may be signs of something serious, even if they aren't causing you pain.

Who is eligible for a Holter and event monitor?

Many heart problems are noticeable only during certain activities. These include exercise, eating, sex, stress, bowel movements, and even sleeping. An electrocardiogram that you can take home is more likely to catch abnormal heartbeats (arrhythmias) than during doctor's visits.

Many people have irregular heartbeats from time to time. These monitors catch patterns like how often they occur, how long they last, and whether they occur at the same time you have symptoms.

What conditions can be diagnosed by a Holter and event monitor?

Holter and event monitoring can help your doctor:

  • Identify irregular heartbeats.
  • Check if your medications work.
  • Check if an implanted pacemaker works.
  • Study symptoms that may be heart-related like palpitations, shortness of breath, dizziness, or fainting.

How do I prepare for a Holter and event monitor test?

If your doctor recommends a Holter monitor, you'll get the device during a scheduled appointment. Plan to bathe before this appointment since most monitors must be kept dry.

What should I expect during my Holter and event monitor test?

Holter Monitor: A technician will place electrodes, or patches, on your chest. The monitor will be connected to the patches with wires and then clipped to your belt or pocket or worn around your neck. After you get instructions, you can return to your usual activities. You will be asked to keep a diary of symptoms.

Event Monitoring: The monitor may be mailed to you with instructions. You will wear two electrodes on your chest connected to the monitor throughout the day, except when bathing. You will return the monitor in a postage-paid envelope. The data will be analyzed and your doctor will review the results with you.
