A cardiac event monitor is a patient-activated option.
Typically worn for 30 days, it is prescribed for patients whose symptoms occur infrequently. When the patient experiences an abnormality, he manually presses a button to record the preceding and following five minutes of the event.
There may also be an auto-capture feature where the device records the information even if the patient is unaware of the activity.
Cardiac event monitors store the recorded data, which is ultimately transmitted either to a physician’s office or to the technician recording station
