A Holter monitor is a small (the size of a cell phone) portable device capable of recording a patients heartbeat. The Holter monitor can be worn from one to two days or up to three weeks (referred to as TAM or event recorder), allowing for evaluation of various arrhythmias. The patients doctor can correlate symptoms of palpitation, flattering or dizziness with actual cardiac electrical activity documented by the Holter monitor.

For complex arrhythmia or infrequent symptoms, a longer period of Holter recording may be needed, which is called an Event Recorder or Mobile Cardiac Outpatient Telemetry (MCOT). Patients wear the Event Recorder or MCOT for up to 21 days of monitoring. When MCOT is used, a remote central office monitors patients 24 hours a day via the small sensor and monitor the patient wears as they continue with their normal daily routine. As events occur, patient activity is automatically transmitted to the central monitoring center for analysis and response.
