The system includes a receiver and a transmitter in an external programmer and a receiver section and transmitter section in the cardiac device. The receiver section and the transmitter section of the cardiac device generally remain in a de-energized state. The receiver section is energized at spaced apart time intervals to detect an initiation signal transmitted by the external programmer. If the initiation signal is detected, the receiver section and the transmitter section of the cardiac device are fully activated. The external programmer includes a signal strength indicating means for providing an indication of received signal strength which the user can use to position the receiver and transmitter in the external programmer for optimum received signal strength. An antenna is disposed in the header of the implanted device to facilitate communication at high speed.Field of SearchRemotely changing, (e.g., programming, pacer) parameters or operationAssurance of security, accuracy, or completion of programming procedure Communicating with pacer (e.g., telemetry) Testing or monitoring pacer function Parameter control in response to sensed physiological load on heart | |
