    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 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.
