1. A medical system for sensing pressure within a blood lumen of a body having a heart, the system comprising:
- an implantable pressure sensor capable of generating an analog blood pressure signal indicative of blood pressure within the lumen; and
an implantable medical device in communication with the pressure sensor, the medical device including an electrocardiogram sensor configured to sense an electrocardiogram signal within the body and determine a rate of the heart, and a control unit configured to determine a sampling rate parameter of the pressure sensor based on the rate of the heart and transmit the sampling rate parameter to the pressure sensor;
wherein the implantable pressure sensor is configured to adjust the rate at which the analog blood pressure signal is digitized based at least in part on the sampling rate parameter received from the medical device.

Abstract
A medical system includes an implantable sensor; and a medical device having a communication link with the sensor. The medical device further including a controller, wherein operating parameters for controlling sampling of a physiological characteristic or other parameter by the implantable sensor are calculated by the controller and communicated to the sensor dynamically.
