    摘要: A method and apparatus are used to provide therapy to a patient experiencing ventricular dysfunction or heart failure. At least one electrode is located in a region associated with nervous tissue, such as nerve bundles T1-T4, in a patient's body. Electrical stimulation is applied to the at least one electrode to improve the cardiac efficiency of the patient's heart. One or more predetermined physiologic parameters of the patient are monitored, and the electrical stimulation is adjusted based on the one or more predetermined physiologic parameters.

    摘要: A method and apparatus for delivering corrective therapy through hormone regulation is provided. Inhibition of sympathetic fibers by spinal cord stimulation is used to regulate the levels of hormones such as catecholamines, renin, and calcitonin gene-related peptide. The invention utilizes a closed or open loop feedback system in which physiological parameters such as the concentrations of hormones and sympathetic indicators such as heart rate and urine production are monitored and used to determine the appropriate level of neurostimulation. The site of electrical stimulation includes, but is not limited to, the spinal cord at levels T7-L2 and the associated neural fibers within a region of the T7-L2 dermatomes.

    摘要: Methods and apparatus of left ventricular pacing including automated adjustment of a atrio-ventricular (AV) pacing delay interval and intrinsic AV nodal conduction testing. Thus, in the event that the AV conduction test reveals a physiologically acceptable intrinsic PR interval then storing the physiologically acceptable PR interval in a memory structure (e.g., a median P-R from one or more cardiac cycles) and delivering fusion pacing using a decremented value of the intrinsic PR interval.

    摘要: The implantable medical device (IMD) system disclosed here utilizes one or more cardiac sensors that measure mechanical characteristics of the heart, such as left ventricular acceleration or right ventricular pressure. The raw sensor data is collected and processed by the IMD, which derives one or more mechanical event marker signals from features, traits, and characteristics of the sensor data waveforms. The mechanical event marker signals are wirelessly transmitted to an external monitor device for display.

    摘要: Delivery of fusion pacing therapy to a later depolarizing ventricle (V2) of a heart of a patient may be timed based on the depolarization of the V2 during at least one prior cardiac cycle. In some examples, a V2 pacing pulse is delivered upon the expiration of a pacing interval that begins at detection of an atrial sense or pace event (AP/S). The pacing interval may be substantially equal to the duration of time between an AP/S and a V2 sensing event of at least one prior cardiac cycle decremented by an adjusted pre-excitation interval (PEI). In another example, the V2 pacing pulse is delivered at the expiration of a pacing interval that begins upon detection of a V2 sensing event of a prior cardiac cycle. The pacing interval may be substantially equal to a duration of time at least two subsequent V2 sensing events decremented by the adjusted PEI.
