The invention relates to devices, systems, and methods for the measurement of a pressure within a body that is adjusted to compensate for variations in local atmospheric pressure. A pressure measurement system can include an implantable target pressure sensor, an implantable internal reference pressure sensor located remotely from the target pressure sensor, an external reference pressure sensor configured to transmit a telemetric signal that is indicative of the local atmospheric pressure, and at least one condition indicator. The implantable medical device system further includes a controller configured to determine a correlation factor based on a signal from the implantable reference pressure sensor and the signal from the external reference pressure sensor. |
