External Cardiac Ambulatory Telemetry

What is it? 

  • It is a small device worn by the patient typically for 2 weeks.

  • Unlike other telemonitoring devices, this allows for a real-time (live) assessment of the patient’s cardiac rhythm. The device continuously transmits raw data and auto analysis to the monitoring center, which can notify the physician for serious arrhythmias. This is very similar to being monitored as a patient in a hospital bed.

  • The patient can also trigger the device if they are having symptoms.

  • The patient should keep a log of their symptoms and activities, with approximate date and time.


  • At the completion of the test, the device is returned to the office. The device is then sent to the manufacturer for data retrieval.

  • Once all the data is available, the doctor will discuss the results with the patient.
