Features of ambulatory electrocardiography devices

Backwards memory—Records data captured before patient activation
Full disclosure—Provides arrhythmia data from the entire recording period
Looping memory—Records over previously captured data, saving only what is pertinent, which reduces the need for extra memory capacity
Multichannel—Records electrocardiographic signals from 2 or more leads simultaneously
Post-event monitor—Recording activated by the patient when an event occurs
Telemetry transmission—Continuously transmits data to a manned remote monitoring station
Wearable device—Electronic device incorporated into a traditional form (eg, smartwatch) that can easily be worn
