What is a Holter Monitor test?

A Holter Monitor is a device that makes a continuous recording of your heart rhythm. It is usually worn for 24 or 48 hours. A Holter Monitor recording lets your doctor see what kind of irregular heart beats you may have, and how often they occur.

How is the test done?

You will have five sticky patches, or electrodes, placed on your chest. Wires from a small recording monitor are attached to the electrodes. The recording box is about the size of a small beeper. You can place this box on your belt with the lead wires underneath your clothing.

You will be given a small diary to record any strange feelings you may have during the time you are wearing the monitor. Please record the time of your symptoms and the exact feeling that you are experiencing in your diary.

The clock in the recorder lets the doctor see exactly what time you have any irregular heart beats. The diary lets the doctor see if your symptoms occur at the same time as the irregular beats.

What do I record in the diary?

  • Palpitations or skips in the heart beat
  • Dizziness or lightheadedness
  • Chest discomforts (tightness, pressure, or pain)
  • Shortness of breath
  • Other unusual symptoms
  • You should also record any unusual activity which may cause a sudden increase in your heart rate such as exercise of hard work.

Can I take a bath or shower while I wear the monitor?

You should not get the monitor or the electrodes wet. The electrodes must be secure on your chest to get a good recording. It is best to take a sponge bath while you are wearing the monitor.

What do I do when it is time for the monitor to come off?

Take the battery out of the monitor and bring or mail the monitor and the battery back to the Centennial Heart Cardiology Consultants.
