    摘要： Devices and methods for therapy control based on electromechanical timing involve detecting electrical activation of a patient's heart, and detecting mechanical cardiac activity resulting from the electrical activation. A timing relationship is determined between the electrical activation and the mechanical activity. A therapy is controlled based on the timing relationship. The therapy may improve intraventricular dyssynchrony of the patient's heart, or treat at least one of diastolic and systolic dysfunction and/or dyssynchrony of the patient's heart, for example. Electrical activation may be detected by sensing delivery of an electrical stimulation pulse to the heart or sensing intrinsic depolarization of the patient's heart. Mechanical activity may be detected by sensing heart sounds, a change in one or more of left ventricular impedance, ventricular pressure, right ventricular pressure, left atrial pressure, right atrial pressure, systemic arterial pressure and pulmonary artery pressure.

    摘要： A system comprising a medical device that includes an impedance measurement circuit adapted to be coupled to implantable electrodes to obtain an intracardiac impedance signal between electrodes, a therapy circuit operable to deliver a therapy to a subject, and a controller circuit coupled to the impedance measurement circuit and the therapy circuit. The controller circuit determines a time rate of change of the intracardiac impedance signal and adjusts at least one parameter related to therapy in a manner that alters the rate of change.

    摘要： This patent document discusses systems, devices, and methods for increasing a sensitivity or specificity of thoracic fluid detection in a subject and differentiating between pleural effusion and pulmonary edema. In one example, a thoracic impedance measurement circuit senses a thoracic impedance signal. In another example, a processor receives the thoracic impedance signal and determines whether such thoracic impedance signal is “significant.” A significant thoracic impedance signal indicates the presence of thoracic fluid and may be recognized by comparing the thoracic impedance signal (or variation thereof) to a thoracic impedance threshold. When a significant thoracic impedance signal is recognized, the processor is adapted to detect one or both of: a pleural effusion indication and a pulmonary edema indication using one or a combination of: physiologic information, patient symptom information, and posture information. In another example, the thoracic impedance threshold is adjusted using such physiologic, patient symptom, or posture information.

    摘要： A gas therapy system involves sensing the blood gas concentration of the patient and adapting a gas therapy based on the sensed gas concentration. Disordered breathing may be detected bases on blood gas concentration, and gas or cardiac electrical therapy may be adapted to treat the detected disordered breathing. One or more of sensing the blood gas concentration, detecting disordered breathing, or adapting the therapy may be performed at least in part implantably. The gas therapy is delivered to the patient through an external respiratory device, such as a positive airway pressure device.

    摘要： A cardiac rhythm management system is capable of treating irregular ventricular heart contractions, such as during atrial tachyarrhythmias such as atrial fibrillation. A first indicated pacing interval is computed based at least partially on a most recent V-V interval duration between ventricular beats and a previous value of the first indicated pacing interval. Pacing therapy is provided based on either the first indicated pacing interval or also based on a second indicated pacing interval, such as a sensor-indicated pacing interval. A weighted averager such as an infinite impulse response (IIR) filter adjusts the first indicated pacing interval for sensed beats and differently adjusts the first indicated pacing interval for paced beats. The system regularizes ventricular rhythms by pacing the ventricle, but inhibits pacing when the ventricular rhythms are stable.
