Event Monitor Overview
An event monitor is a portable device used to record your heart’s electrical activity when you have symptoms. It records the same information as an electrocardiogram (ECG), but for longer durations of time. Most of these devices can transmit the recorded information directly to your healthcare provider. This allows him or her to analyze the electrical activity of your heart while you are having symptoms.
How do I prepare for using an event monitor?
Your healthcare provider will show you how to use your event monitor. There are different types of event monitors that all work in different ways.
Cardiac memory loop monitors have sensors that attach to your chest using sticky patches. Wires connect these sensors to a monitor, which you can usually put on your belt or in your pocket. Before you put your sensors on your chest, your skin should be free of oils, creams, and sweat. Clean your skin before putting them on. You may need to shave the area before applying. A technician will show you how to place the electrodes.
What happens after using an event monitor?
Ask your doctor about what you can expect after you use an event monitor.
After a few readings, you may be able to stop wearing your event monitor. Your healthcare provider may use those readings to start your treatment. In some cases, more testing maybe needed. Follow-up tests might include:
Tilt-table test, if you have had fainting
It is best to check with the center where you are having your test for specific information about how to prepare.
Setting up the monitor only involves a few minutes and then you can go about your regular daily activities.
You may be asked to write down any symptoms you have while wearing the monitor so your heartbeat at that particular time can later be analyzed.
