A Cardiac Outpatient Telemetry monitor, also referred to as Mobile Cardiovascular Telemetry, is a device that continuously records the electrical activity of the heart for up to 30 days. The Cardiac Outpatient Telemetry monitor is attached to the patient's chest by 3 leads and records every beat for the entire study.

The patient can trigger a recording at any time by pushing the Record event button on the Cardiac Outpatient Telemetry monitor. The event will then be sent over cellular networks to a lab where the recording is edited and sent to the patient's physician. Recordings may also be automatically triggered by cardiac arrhythmia.

When using Cardiac Outpatient Telemetry physicians have access to a recording of every heart beat throughout the extended study. The physician utilizes the collected data to diagnose and recommend further treatment for the patient.

Some physicians and insurance companies may refer to this monitor as a Mobile Cardiovascular Telemetry monitor.
