What is a cardiac event monitor?

A cardiac event monitor helps to diagnose heart arrhythmias, which are heart rhythm problems. The small, battery-operated recorder device is given to you to wear for several weeks during your daily routine, with the goal of wearing the monitor as much as possible to ensure you are able to capture rhythm irregularities. When the monitor is attached to you, each time you experience symptoms (weakness, fatigue, palpitations, low blood pressure, dizziness, fainting), press the button on the device to record the EKG/ECG sample. These samples can be transmitted over the phone back to your physician, who will evaluate the results.

What to expect during cardiac event monitor testing

Preparing for your procedure

The day of your appointment to hook up your cardiac event monitor, please do not use moisturizing cream or lotion on your chest. Lotion makes it more difficult for the patches to stick to your skin.

During your procedure

It is important to wear the cardiac event monitor whenever possible, so that it can accurately record your heartbeat. The monitor cannot get wet, so make sure to take it off when you shower or swim. You will be given extra patches to use as needed after showering. If you find that your skin is sensitive and reacts to the adhesive of the patches, be sure to call your physician’s office to request hypoallergenic patches. If any heart rhythm abnormalities are detected while you are wearing the monitor, you may be contacted by the monitoring company or your physician’s office.

After your procedure

Your physician will discuss the cardiac event monitor test results with you and determine the appropriate next steps.
