Cardiac Event Recorder / Memo
Cardiac event recorders do not record every heart beat. Instead, event recorders use a ‘loop’ system that stores only approximately 30 seconds of a patient's heart rhythm. So, at any given time while a patient is wearing them, event recorders will have the most recent 30 seconds of the patient's ECG. When the patient experiences the symptom of interest, he/she presses a button that freezes the recording. A major advantage of event recorders is that they can be used for 1-6 weeks, or until the symptom being looked for occurs.
