Holter Loop Monitoring - DR400

The monitor is a small, portable device that attaches to a patch and is then placed on your chest. It is lightweight and can be worn in the shower. Specific instructions on the care of the device will be given to you at the time you receive the monitor. You will be asked to wear it from 24 hours to 14 days, depending on your physician’s request. The monitor can be picked up at one of our locations or mailed out to you.

How to Prepare for Your Test

Can I eat or drink on the day of the test?

Yes. Eat and drink as you normally would the day of the test.

Should I take my medications on the day of the test?

Take all of your medications at the usual times, as prescribed by your doctor.

What should I wear on the day of the test?

Wear comfortable clothing. You will need to remove your shirt in order to have the monitor placed if you are coming to the office.

What Happens During the Test?

The technologist will explain how the device works and what to do if the patch needs to be replaced. You will receive instructions on how to place the device and when/where to return it.

How Will I Feel During the Test?

You should feel no discomfort during the time that you wear the monitor. If the patch becomes loose due to sweating or comes off at any time you should replace it with an extra patch that will be provided.

What if I am having an allergic reaction while wearing a Holter Monitor?

The patch and electrodes are hypoallergenic and latex-free and reactions are rare. If you do experience sensitivity or a rash, you should remove the patch/electrodes immediately and call the office. You will return the device and we will analyze the data that was recorded to see if we have enough information to provide a report.

If you are to wear a Holter monitor for several days, let the technologist know you have allergies and they will provide you with stickers for sensitive skin.

How and when do I return the monitor?

The monitor can be returned to one of our locations during normal hours of operation. There is a drop box located just outside of our office on the 2nd floor of the Windsor location. Devices can also be mailed back to us. Talk to the technologist when you get the device placed to determine the best way to return it to us. The faster we get the device back, the sooner your doctor will get the results.

How do I get the results of my test?

After a cardiologist has reviewed your test, the results will be sent to the referring physician and your family doctor. If a consult has been requested, you will also have an appointment to speak to a cardiologist who will discuss the results of the exam with you. This appointment may or may not occur on the same day as your exam.
