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. A method and device for applying reverse hysteresis and mode switching to the delivery of such cardioprotective pacing are described.

摘要： This document discusses, among other things, an apparatus comprising at least one implantable cardiac depolarization sensing circuit, an electrical stimulation circuit, and a pacing mode controller. The implantable cardiac depolarization sensing circuit is configured to obtain a sensed depolarization signal from a ventricle and the electrical stimulation circuit is configured to provide pacing electrical stimulation energy to at least one implantable ventricular electrode. The pacing mode controller delivers pacing therapy according to a first pacing mode that is a normal operating mode, and delivers 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 switched from the normal operating mode to a stress augmentation mode.

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.
