Cardiac Event Monitor
Your doctor has asked that you have a cardiac event monitor. This pamphlet answers some of the questions you may have about the test.
Purpose of the test:
- To check the heart rate (number of beats per minute).
- To check the regularity of the beats (the heart rhythm)
Description of the test
A Cardiac Event Monitor (also called King of Hearts) measures the electrical activity of the heart and is loaned to you for a period ranging from several days to two weeks. It is used to detect abnormal heart rhythms that may be occurring when you are experiencing symptoms (such as shortness of breath, irregular heart beats, chest pain, etc). An appointment is booked for you to come in to have the monitor hooked up. The skin is cleaned and if necessary shaved. The skin is gently scraped to get the best possible connection. Two or three electrodes (adhesive patches) are applied to the chest area and are attached to the monitor. You will be instructed on how to replace the electrodes as needed. You will receive instructions on how to push the “record button” on the recorder when you are feeling symptoms and on how to transmit the recorded events via the telephone to the Cardiology Lab. Once transmitted, the recordings can be printed and checked by the cardiologist for anything abnormal. During this time you will be asked to do your normal activities. You will be given a supply of extra electrodes, batteries and tape so that you will be able to change and move the location of the electrodes to prevent skin rash. You will be able to remove the monitor each day to bath or shower. While the monitor is on you MUST keep it away from moisture.
What preparation is required?
- Have a bath or shower the morning of the test.
- Do not put lotions or powders on your skin.
- Wear a loose fitting blouse or shirt that buttons down the front.
- Women should wear a comfortable bra; no long-line or full slips.
How long will the test take?
Allow one hour for the monitor to be put on. You will be asked to return the monitor at a pre-arranged date or after enough information has been gathered. Allow one hour for the monitor to be removed. Allow 2 hours for parking in case of delay.
After the test?
Some people may develop a slight rash where the electrodes were placed. You can resume your regular activities.
