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 pacing system delivers cardiac protective pacing therapy (CPPT) to protect the heart from injuries and/or to treat existing injuries. The pacing system receives a set of inputs and delivers optimized cardiac protection pacing tailored for different purposes. The system delivers electrical stimulation to modulate myocardial strain for anti-atherosclerosis therapy and/or to provide therapy for myocardial infarction (MI). In one embodiment, a medical device for treating atherosclerosis is provided. The medical device includes a sensing circuit to receive sensed signals to identify areas of coronary artery disease (CAD) or areas at risk for CAD using the sensed signals. The device also includes a pacemaker circuit adapted to deliver an electrical signal through at least one electrode to a myocardial target adjacent to the identified areas. According to various embodiments, a controller communicates with the sensing circuit and controls the pacemaker circuit to provide intermittent electrical stimulation to the myocardial target to induce periods of stretch on the vessel due to induce myocardial strain changes. The stimulation is targeted to attenuate or prevent atherosclerosis associated with the CAD, according to various embodiments.

摘要： Stimulation energy can be provided to a His-bundle to activate natural cardiac contraction mechanisms. Interval information can be used to describe a cardiac response to His-bundle stimulation, and the interval information can provide cardiac stimulation diagnostic information. For example, interval information can be used to discriminate between intrinsic conduction cardiac contractions and contractions responsive to His-bundle pacing.

摘要： A method and apparatus is described for detecting and localizing areas of myocardial infarction or ischemia. By pacing sites in proximity to the infarcted or ischemic region with appropriately timed pacing pulses, the region is pre-excited in a manner that lessens the mechanical stress to which it is subjected, thus reducing the metabolic demand of the region and the stimulus for remodeling.
