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 have been provided. Please refer to instructions provided by the technologist or see instructions here.

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 be asked to return the device and we will analyze the data that was recorded to see if we have enough information to provide a report. The test may need to be repeated.

How and when do I return the monitor?

The monitor should be returned to one of our locations listed below during normal hours of operation. There are drop boxes located outside of our three offices. Alternatively, 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.

Please be sure to include the red wire and any unused supplies. The faster we get the device back, the sooner your doctor will get the results.

I am unable to return my monitor. What should I do?

We are here to help. If you are unable to return the monitor to us for any reason, please give us a call so we can assist you and find a solution.

Failure to return the monitor will result in you being responsible for its replacement value.

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.

I have had a reaction to the patch?

We recommend you use polysporin and contact your physician to seek advice on the best way to reduce redness and any discomfort.
