摘要： The disclosure describes techniques for quantifying the autonomic nervous system (ANS) health of a patient with thoracic impedance measurements. Thoracic impedance may be measured utilizing cardiac electrodes and an implantable medical device housing or other electrodes located on or within the patient. Since greater variability in thoracic impedance may indicate better health of the ANS, monitoring impedance changes in a patient may be used to quantify autonomic tone of the ANS, and ultimately, overall patient health. In some examples, thoracic impedance may be measured in response to a change in patient posture for acute monitoring or at predetermined times over several days, weeks, or months for more chronic monitoring of the patient. An implantable medical device may independently analyze the impedance measurements and transmit an alert to the patient or clinician when impedance changes indicate a change in patient health.

摘要： In one embodiment, a system includes a video mixer coupled with an audio mixer for exchange of information that includes a first set of delay values respecting input audio streams received by the audio mixer from a plurality of source endpoints, and output audio streams sent from the audio mixer to a plurality of destination endpoints. The information further including a second set of delay values respecting the corresponding input video streams. The audio mixer calculates end-to-end video delays, and the video mixer calculates end-to-end audio delays. The audio mixer delays the output audio streams to equalize the end-to-end audio and video delays in the event that the end-to-end audio delays are less than the end-to-end video delays, and the video mixer delays the output video streams to equalize the end-to-end audio and video delays in the event that the end-to-end video delays are less than the end-to-end audio delays.

摘要： Techniques for using multiple physiological parameters to provide an early warning for worsening heart failure are described. A medical device monitors a primary diagnostic parameter that is indicative of worsening heart failure, such as intrathoracic impedance or pressure, and one or more secondary diagnostic parameters. The medical device detects worsening heart failure in the patient based on the primary diagnostic parameter when an index that is changed over time based on the primary diagnostic parameter value is outside a range of values, termed the threshold zone. When the index is within the threshold zone, the medical device detects worsening heart failure in the patient based on the one or more secondary diagnostic parameters. Upon detecting worsening heart failure, the medical device may, for example, provide an alert that enables the patient to seek medical attention before experiencing a heart failure event.

摘要： Providing a conference call includes establishing a bidirectional first class stream for each of a set of first class endpoints. A second class stream is established for each of a set of second class endpoints. Mixed streams are generated using the bidirectional first class streams, and one or more mixed streams are broadcasted to the set of second class endpoints. A particular second class endpoint is determined to have a right to have its stream included in the mixed streams. The second class stream for the particular second class endpoint is mapped to a bidirectional second class stream for the particular second class endpoint. Next mixed streams are generated using the bidirectional second class stream.

摘要： A multi-layer method for detecting atrial arrhythmias using ventricular cycle length information that includes performing a base layer algorithm for detecting the onset and offset of an atrial tachyarrhythmia. The multi-layer method further includes one or more higher layer algorithms executed in response to a base layer detection to confirm or reject the base layer detection. The base layer is designed to operate with high sensitivity to atrial fibrillation and/or organized atrial tachycardia and the higher layer is designed to operate with high sensitivity and high specificity to atrial fibrillation and/or organized atrial tachycardia.
