    Abstract: A device can include a multi-dimensional posture sensor that provides an electrical sensor output representative of alignment of first, second, and third non-parallel axes of the device with the gravitational field of the earth, and a processor that includes a calibration circuit and a posture circuit. The calibration circuit measures a first sensor output for the first device axis and a second sensor output for one of a second device axis while the subject is in a first specified posture, measures sensor outputs for the first, second, and third device axes while the subject is in a second specified posture, calculates one or more coordinate transformations, generates transformed sensor outputs using the coordinate transformations, and calibrates the posture sensor by calculating a calibration transformation using the first and second sensor outputs and the transformed sensor outputs. The posture circuit determines a subsequent posture of the subject using the posture sensor.

    Abstract: An implantable system for ambulatory monitoring of a high-risk heart failure patient includes a first pressure sensor (12) implantable within an abdomen of the patient for sensing and generating an output representative of a baseline intra-abdominal pressure value of the patient and for chronically sensing and generating an output representative of an intra-abdominal pressure value of the patient at periodic intervals. At least one second implantable sensor (18) is provided for sensing and generating an output representative of a second physiological parameter of the patient. Additionally, the system includes a processor for correlating the output of the first pressure sensor and the second physiologic sensor, and for comparing differences between the baseline intra-abdominal pressure value and subsequent intra-abdominal pressure values. The processor can reside in another implantable device (14) or in an external device/system (16).

    Abstract: An implantable or other ambulatory medical apparatus comprises a posture sensing circuit, a physiologic sensing circuit that senses a time varying physiologic signal, and a processor circuit. The processor circuit includes a posture calculation circuit and a measurement circuit. The posture calculation circuit determines a posture of the subject using posture data obtained using the posture signal and determines when the posture of the subject is steady state. The measurement circuit derives a physiologic measurement using physiologic data extracted from the physiologic signal during at least one time period when posture is determined to be steady state and provides the physiologic measurement to at least one of a user and a process in association with the determined steady state posture.
