摘要： Systems and methods for diagnosing one or more respiration distress manifestations by implantably recognizing their occurrence and evaluating information about the same to provide an indication of present or impending worsening heart failure are discussed. Using information produced by an implantable respiration sensor circuit and an implantable physiological sensor circuit, such as at least one of a physical activity sensor circuit or a posture sensor circuit, an implantable or external processor circuit may detect a respiration disturbance and an associated subsequent arousal from stable state occurrence and thereafter evaluate over time arousal from stable state occurrences to provide the indication of present or impending worsening heart failure. In one example, information about a fluid level within a subject is used in determining the indication of worsening heart failure. In various examples, a regimen is initiated or adjusted in response to the indication of present or impending worsening heart failure.

摘要： Disordered breathing events may be classified as central, obstructive or a combination of central an obstructive in origin based on patient motion associated with respiratory effort. Central disordered breathing is associated with disrupted respiration with reduced respiratory effort. Obstructive disordered breathing is associated with disrupted respiration accompanied by respiratory effort. A disordered breathing classification system includes a disordered breathing detector and a respiratory effort motion sensor. Components of the disordered breathing classification system may be fully or partially implantable.

摘要： Systems and methods for monitoring pulmonary edema or other thoracic fluid status in a subject use thoracic impedance histogram information. An internal or external processor circuit receives the thoracic impedance histogram information and uses it to compute and provide a lung fluid status indication. The thoracic impedance histogram information can include a count, mean or median of a histogram bin or subrange of bins within the histogram range.

摘要： An apparatus comprises plurality of sensors and a processor. Each sensor provides a sensor signal that includes physiological information and at least one sensor is implantable. The processor includes a physiological change event detection module that detects a physiological change event from a sensor signal and produces an indication of occurrence of one or more detected physiological change events, and a heart failure (HF) detection module. The HF detection module determines, using a first rule, whether the detected physiological change event is indicative of a change in HF status of a subject, determines whether to override the first rule HF determination using a second rules, and declares whether the change in HF status occurred according to the first and second rules.

摘要： The health state of a subject is automatically evaluated or predicted using at least one implantable device. In varying examples, the health state is determined by sensing or receiving information about at least one physiological process having a circadian rhythm whose presence, absence, or baseline change is associated with impending disease, and comparing such rhythm to baseline circadian rhythm prediction criteria. Other chronobiological rhythms beside circadian may also be used. The baseline prediction criteria may be derived using one or more past physiological process observation of the subject or population of subjects in a non-disease health state. The prediction processing may be performed by the at least one implantable device or by an external device in communication with the implantable device. Systems and methods for invoking a therapy in response to the health state, such as to prevent or minimize the consequences of predicted impending heart failure, are also discussed.

摘要： Devices and methods for detecting disordered breathing involve determining that the patient is asleep and sensing one or more signals associated with disordered breathing indicative of sleep-disordered breathing while the patient is asleep. Sleep-disordered breathing is detected using the sensed signals associated with disordered breathing. The sensed signals associated with disordered breathing may also be used to acquire a respiration pattern of one or more respiration cycles. Characteristics of the respiration pattern are determined. The respiration pattern is classified as a disordered breathing episode based on the characteristics of the respiration pattern. One or more processes involved in the detection of disordered breathing are performed using an implantable device.

摘要： An apparatus comprises a physiologic sensing circuit and a control circuit. The physiologic sensing circuit is configured to sense an electrical respiration signal representative of respiration of a subject. The control circuit includes a respiration monitor circuit and a therapy circuit. The respiration monitor circuit is configured to extract a respiration parameter from the respiration signal and detect that a value of the respiration parameter is outside of a target value range for the respiration parameter. The therapy circuit is configured to deliver neural stimulation to the carotid sinus of the subject to stimulate respiration and to adjust respiration to maintain the value of the respiration parameter within the target value range.
