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： 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： 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.

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 pacing system delivers cardiac protection pacing to protect the heart from injuries. The pacing system receives a set of inputs and calculates parameters for delivering optimized cardiac protection pacing tailored for different stress levels. The system automatically adjusts heart rate to optimize cardiac protection pacing in a closed-loop system. In one embodiment, a method for delivering pacing pulses for cardiac protection is provided. Intrinsic atrioventricular (AV) intervals are sensed. The intrinsic AV interval and a predetermined equation relating the AV interval to an optimal AV delay are used to provide a maximum positive rate of left ventricular pressure change during systole. An AV delay is calculated using a predetermined percentage of the optimal AV delay to deliver ventricular pacing pulses to provide a desired level of stress for cardiac protective pacing therapy (CPPT) to provide a cardiac conditioning therapy to improve autonomic balance.

摘要： Systems and methods facilitate placement of a lead in or on a patient's heart. At least one reference sensor is positioned at a right heart location of a patient's heart and a cardiac lead apparatus comprising at least one lead apparatus sensor is advanced to a plurality of left heart locations. Using the reference sensor and the lead apparatus sensor, a distance parameter indicative of a distance between the reference and lead apparatus sensors is measured for each of the plurality of left heart locations. Strain or stress estimates are determined for the plurality of left heart locations derived from the distance parameter measurements. Using the strain or stress estimates, a physician perceivable output is produced indicating suitability of the left heart locations as pacing sites.

摘要： A device and method for delivering electrical stimulation to the heart in order to improve cardiac function in heart failure patients. The stimulation is delivered as high-output pacing in which the stimulation is excitatory and also of sufficient energy to augment myocardial contractility. In order to provide a consistent hemodynamic response, the high-output pacing is optimized by delivering it using different parameter sets, evaluating the hemodynamic response thereto as reflected by one or more measured physiological variables, and selecting the parameter set with the best hemodynamic response.

摘要： Methods and devices are described for delivering electrical stimulation to the heart in a manner that advantageously redistributes myocardial stress during systole for therapeutic purposes in the treatment of, for example, post-MI and HF patients. Pre-excitation pacing may be applied to deliberately de-stress a particular myocardial region that may be expected to undergo deleterious remodeling, such an the area around a myocardial infarct or a hypertrophying region or to deliberately stress a region remote from the pre-excitation pacing site in order to exert a cardioprotective conditioning effect, similar to the beneficial effects of exercise. Pre-excitation pacing may be advantageously combined with inotropic electrical stimulation applied to the stressed region.
