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 |
