Holter monitoring

Holter monitor

At the LIEPA Medical Center, you have the opportunity to undergo Holter monitoring.


What is a Holter monitor?
A Holter monitor is a small, battery-operated medical device used to measure the rate and rhythm of your heart. It is also used to diagnose other abnormalities that may affect the normal functioning of your heart. During a routine electrocardiogram (ECG), electrodes are placed on your chest to check your heart rhythm. However, not all heart rhythm abnormalities may be seen at this brief moment. A Holter monitor is used to measure your heart rhythm and rate over a 24- or 48-hour period, and the patient can continue to perform daily activities while wearing it. The device is quick and painless to put on. Disposable electrodes are placed on the client’s chest under their clothing, and a heart recorder is attached to them and is attached to a belt. Holter monitoring is sometimes called ambulatory electrocardiography.

When is Holter monitoring recommended?

  • You have a slow, fast, or irregular heartbeat.

  • You are starting a new heart medication, or your doctor needs to determine if your medication is working properly.

  • You have a pacemaker and your doctor wants to make sure it is working properly.

  • The results of your electrocardiogram (ECG) are not within normal limits.

  • You have had a heart attack.

  • You are scheduled for heart surgery.

How is a Holter monitor installed?

  • Your doctor will place special stickers on your chest area to which electrodes are attached. In some cases, you may experience skin irritation or a rash where the electrodes are attached. Tell your doctor if you are allergic to any type of adhesive or patches.

  • The electrodes are connected to a monitor that will continuously record the electrical signals. The monitor is placed in a small case and you can take it with you. It is recommended to wear loose clothing when using the monitor.


What else should you know about using a Holter monitor?


While using a Holter monitor, pay attention to how you feel. Note the time and what you were doing when the unpleasant feelings started. Write down when you took any medications or drank any alcoholic beverages. These notes can help your doctor determine what is causing your heart to beat abnormally. Here are some examples of the types of feelings you should record:

  • chest pain or discomfort;

  • dizziness or fainting;

  • irregular heart rhythm;

  • shortness of breath or difficulty breathing;

  • palpitations.


Avoid getting your breasts wet while the electrodes are attached. If the patches get wet, they may fall off. The monitor cannot record your heart rate if the patches and electrodes are not in place. The monitor may stop if it gets wet. Do not expose yourself to X-rays while using the monitor. Avoid metal detectors, do not use an electric blanket. These devices can interfere with the monitor.

Return the Holter monitor to your doctor as instructed. The doctor will process the monitor information, your notes, and inform you of the results.
