An event recorder is a type of testing that allows a patient to record periods of electrical activity of the heart over a period of several weeks. The procedure is performed to identify abnormal beats and heart rhythms; evaluate your symptoms in relation to your heart beat; monitor pacemaker or defibrillator activity; and assess if your medications are related to your symptoms over a long period of time.
The event recorder test allows for on-demand heart monitoring during a patient’s normal activities. When the patient experiences an episode of dizziness, weakness or palpitation, he or she will push the button on the device, which stores the data. Following the testing period, the monitor is returned to your physician to record data.
