What is
Loop Event Monitoring?
Similar to a Holter, this device is an event monitor with a looping memory which allows the last few minutes of recording to be saved along with several minutes of real-time recording, whenever the event marker button is depressed, usually at the time a symptom. Worn for 7-30 days, most versions of this test do not capture the ECG between activations, although some devices do have the capability to automatically detect and record a set of specified rhythm disturbances.
What to Expect
—
The skin is cleaned and the electrodes are attached firmly to the chest. The device is worn under clothes, either on a belt or around the neck. You will be asked to record symptoms and activities in a diary and to depress the event marker on the device in case of symptoms. For longer-term recordings you will be provided with additional electrodes to allow you to remove the recorder to take a shower.
