    摘要: An implantable medical device system including a physiological sensor detects signal artifact in a signal waveform acquired by the sensor. Features of individual waveforms in the sensor signal are extracted. Sample waveforms are classified by expert observation into at least two classes including an artifact class. A distribution range for each of the extracted features from the sample waveforms is determined for each of the classes. Waveform classification criteria are established in response to the determined distribution ranges.

    摘要: A system and method are provided for determining an index of autonomic nervous system (ANS) or sympathetic nervous system (SNS) activity for use in patient monitoring or therapy delivery control. An ANS or SNS index is calculated as a function of multiple monitored physiological variables that strongly correlate to changes in autonomic or sympathetic tone. These ANS-influenced variables are derived from selected hemodynamic and/or electrical signals and may include variables relating to any of: the maximum rate of pressure rise (dP/dtmax), the maximum rate of pressure decline (dP/dtmin), pulse pressure (PP), pre-ejection time interval (PEI) and/or systolic time interval (STI), heart rate (HR), heart rate variability (HRV), and baro-reflex gain. Changes in the ANS or SNS index may be used to automatically adjust a device delivered therapy.

    摘要: A medical device system including a physiological sensor is configured to perform a method for detecting signal artifact in a signal waveform acquired by the sensor. A signal waveform is sensed in a patient using the physiological sensor and a fiducial point associated with the sensed waveform is identified. A point value is established using the fiducial point. Signal artifact is detected in response to the established point value and an established threshold, and at least a portion of the signal waveform is rejected in response to detecting signal artifact.

    摘要: A therapy regimen, e.g., a contingent medication prescription, may be created and automatically distributed to a patient via an integrated patient care system. A clinician may create therapy instructions by at least associating patient conditions with one or more therapy regimens, e.g., medication prescriptions. In some examples, the integrated patient care system may present historical condition data to the clinician to aid the clinician with creating and/or updating the therapy instructions specific to the patient. A therapy module of the integrated patient care system may use the therapy instructions to automatically select a therapy regimen from the therapy instructions based on a patient condition detected based on a sensed physiological parameter. The physiological parameter of the patient may be sensed by an implanted or external sensor. In some examples, the therapy regimen can be presented to the patient according to a predetermined schedule or in response to the detected condition.

    摘要: The present invention provides a system and method for estimating a blood flow waveform contour from a pressure signal. An arterial or ventricular pressure signal is acquired from a pressure sensor. Landmark points are identified on the pressure waveform that correspond to features of a flow waveform. In one embodiment, the landmark pressure waveform points correspond to the onset of flow, the peak flow, and the end of the systolic ejection phase. The landmark pressure waveform points define a contour that approximates the flow contour. Beat-by-beat flow contour estimation can be performed to allow computation of flow-related hemodynamic parameters such as stroke volume or cardiac output for use in patient monitoring and/or therapy management.
