telemetry
Wireless communication between an implanted cardiac device and external monitoring or programming equipment.
Full Definition
Telemetry in cardiac devices refers to the bidirectional wireless communication that enables data transfer between implanted devices and external equipment without direct physical connection. This technology allows remote interrogation of device status, retrieval of stored diagnostic data, and programming parameter changes. Modern telemetry systems operate using radiofrequency or Bluetooth protocols and can function at distances from close proximity to several meters. Remote telemetry capabilities enable home monitoring, reducing clinic visits while providing continuous surveillance for device function and patient status. The technology also facilitates emergency alerts and trending of physiological parameters over time.
Usage
Usage note: Distinguish between device telemetry and hospital cardiac telemetry monitoring systems.
In Context
- "The device's telemetry function transmitted an alert when the patient experienced atrial fibrillation." — Remote monitoring report
- "Telemetry range varies by manufacturer, with some systems effective up to ten feet from the device." — Technical manual
