摘要： Various system embodiments comprise a myocardial stimulator, at least one sensor adapted for use in detecting heart rate to determine heart rate turbulence (HRT), and a controller connected to the myocardial stimulator and the at least one sensor. The myocardial stimulator is adapted to deliver pacing pulses through at least one electrode to provide cardiac pacing. The controller is adapted to intermittently deliver a sequence of stress-inducing pacing pulses adapted to increase sympathetic tone during the stress-inducing pacing. The controller is further adapted to determine HRT from the detected heart rate to assess cardiac stress to the stress-inducing pacing pulses, and adjust at least one parameter of the stress-inducing pacing pulses to adjust cardiac stress if the cardiac stress to the stress-inducing pacing pulses is undesirable.

摘要： This document discusses, among other things, an apparatus comprising an implantable cardiac depolarization sensing circuit, an electrical stimulation circuit, and a pacing mode controller. The pacing mode controller is configured to deliver pacing therapy according to a first pacing mode that is a normal operating mode, and to deliver pacing therapy according to second and third pacing modes. The second and third pacing modes increase mechanical stress on at least a particular portion of the ventricle as compared to the pacing therapy delivered during the first pacing mode. The pacing mode controller alternates between the second and third pacing modes when pacing is changed from the normal operating mode to a stress augmentation mode. The pacing mode controller suspends the change from the normal operating mode to the stress augmentation mode when a condition to prevent the change is detected.

摘要： A cardiac pacing system controls the progression of a cardiac disorder such as heart failure by delivering cardiac pacing to create or augment regional stress in the heart. The cardiac pacing is delivered intermittently, such as on a periodic basis, according to a cardiac stress augmentation pacing sequence that includes alternating pacing and non-pacing periods. One or more physiological signals are monitored for closed-loop control of the cardiac pacing using baseline characteristics of the cardiac disorder, acute cardiac stress created by the cardiac pacing, and/or risk associated with the cardiac pacing.

摘要： A method and device for treating myocardial ischemia are described in which the stress experienced by a myocardial region identified as vulnerable to becoming ischemic is varied with pre-excitation pacing. In an unloading mode, pacing is applied in proximity to the vulnerable region to reduce stress and the metabolic demand of the region. In a loading mode, pacing is applied to a region remote from the vulnerable region in order to produce a conditioning effect.

摘要： A device and method for delivering pacing therapy to the heart in order to improve cardiac function in heart failure and post-MI patients. The pacing therapy is delivered in a manner that mimics the effects of exercise and improves symptoms even in patients who are exercise intolerant. The simulated exercise pacing may be delivered on an intermittent basis in accordance with a defined schedule and/or in response to detected conditions or events.

摘要： An apparatus comprises an implantable sensor and a detection circuit. The implantable sensor provides a physiologic sensor signal and is to be positioned at a lymph node of a subject. The detection circuit detects a change in a physiologic parameter of the lymph node that exceeds a threshold change, and deems that the change in the physiologic parameter indicates a change in inflammation of an organ associated with the lymph node.

摘要： Cardioprotective pre-excitation pacing may be applied to stress or de-stress a particular myocardial region delivering of pacing pulses in a manner that causes a dyssynchronous contraction. Such dyssynchronous contractions are responsible for the desired cardioprotective effects of pre-excitation pacing but may also be hazardous. Described herein is a method and system that uses measures of a patient's heart rate or exertion level to control the duty cycles of intermittent pre-excitation pacing.
