    摘要: The invention relates to systems, devices, and methods for detecting infections associated with implantable medical devices. In an embodiment, the invention includes a method of detecting infection in a patient including measuring a physiological parameter using a chronically implanted sensor at a plurality of time points and evaluating the physiological parameter measurements to determine if infection is indicated. In an embodiment, the invention includes an implantable medical device including a first chronically implantable sensor configured to generate a first signal corresponding to a physiological parameter and a controller disposed within a housing, the controller configured to evaluate the first physiological parameter signal to determine if an infection is indicated. Other embodiments are also included herein.

    摘要: Optimizing cardiac preload based on measured pulmonary artery pressure involves varying, for each repetition of an acute burst protocol, a parameter of pacing applied to a patient's heart during the acute burst protocol. Pulmonary artery pressure is measured during the repetitions of the acute burst protocol. The length of the repetitions is chosen so that the patient's baroreflex system does not adjust to the varied parameter of pacing during the repetitions of the acute burst protocol. An optimum ventricular preload is determined based on the measured pulmonary artery pressure. Pacing therapy is provided using a value of the parameter that is selected based on the determination of optimum ventricular preload.
