    摘要: 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.

    摘要: Physiological data, such as thoracic impedance data, can be obtained over a first time window to establish a baseline, or can be used to form one or more data clusters. Additional physiological data, such as thoracic impedance test data acquired over a later time window, can be obtained and compared to the baseline or data clusters to determine an indication of worsening heart failure. In an example, a quantitative attribute of one or more data clusters can be monitored and used to provide an indication of worsening heart failure. A posture discrimination metric can be obtained, such as using the physiological data obtained over the first time window. The additional physiological data, such as can be obtained over a second time window, can be compared to the posture discrimination metric to provide a patient posture status.

    摘要: Devices and methods for improving the sensitivity and specificity of heart failure (HF) detection are described. The devices and methods can detect a HF status such as using physiological sensor data and external biomarker assays. An apparatus can comprise ambulatory physiological sensors that can provide a first HF status indicator and a second HF status indicator to a user. An external biomarker sensor can provide an amount of a biomarker present, such as an assay for B-type natriuretic peptide (BNP), which provides information about HF status. A processor circuit can switch from a first HF detection mode to a second detection mode such as in response to the information from the biomarker sensor. The first detection mode can detect HF status using the first HF status indicator, and the second detection mode can detect HF status using the second HF status indicator. The second detection mode can have a higher specificity than the first detection mode.

    摘要: A differential or relative measurement between an orthogonal measurement vector and another measurement vector can be used to determine the location where fluid accumulation is occurring or the local change in such fluid accumulation. This can help diagnose or treat infection or hematoma or seroma at a pocket of an implanted cardiac rhythm management device, other implanted medical device, or prosthesis. It can also help diagnose or treat pulmonary edema, pneumonia, pulmonary congestion, pericardial effusion, pericarditis, pleural effusion, hemodilution, or another physiological condition.
