Zusammenfassung:The invention presents techniques for reducing the interference to telemetry from an implanted medical device caused by a source of controllable noise. I n 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 f or suspending energy storage operation gradually rather than abruptly, by gradually reducing the duty cycle of a clock that controls the energy storag e.
