Zusammenfassung: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.
