摘要： An implantable pacing device for delivering ventricular pacing may be configured to intermittently reduce the AVD interval for beneficial effect in patients with compromised ventricular function (e.g., HF patients and post-MI patients). The AVD interval may be reduced in an AVD reduction mode, by shortening the AVD in an atrial triggered ventricular pacing mode or by switching to a non-atrial triggered ventricular pacing mode (e.g., VVI) and delivering paces at a rate above the intrinsic rate. The physiological effects of AVD reduction may be either positive or negative on cardiac output, depending upon the individual patient.

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 implantable cardiac rhythm management (CRM) device delivers a chronic therapy while detecting an ischemic state. When the ischemic state indicates the occurrence of an ischemic event, the implantable CRM device delivers a post-ischemia therapy. The post-ischemia therapy and the chronic therapy are adjusted using feedback control with the ischemic state and parameters indicative of the effectiveness of the post-ischemic therapy and the effectiveness of the chronic therapy as inputs.

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： 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.
