A method and apparatus for providing status of a parameter that includes detecting an alert level of a parameter monitored by an implanted medical device, transmitting data corresponding to the detected alert level from the implanted medical device to an external monitor, scheduling a follow-up interrogation session after receiving transmitted data corresponding to the detected alert level, and retrieving updated data from the implanted medical device corresponding to the monitored parameter during the follow-up interrogation session.

Automatic parameter status on an implantable medical device system

The invention presents techniques for reducing the interference to telemetry from an implanted medical device caused by a source of controllable noise. In the context of an implanted system that includes a defibrillator system and a telemetry system, for example, the invention reduces the interference by suspending energy storage during telemetry. The invention further provides for suspending energy storage operation gradually rather than abruptly, by gradually reducing the duty cycle of a clock that controls the energy storage.
