    摘要: Methods and devices for delivering cardiac therapy to a patient are provided. Various implantable device embodiments comprise a plurality of leads and a controller. The leads include at least one lead to be positioned within a lead path to deliver ventricular pacing pulses and to deliver neural stimulation at a site proximate to the heart to inhibit sympathetic nerve activity. The controller controls delivery of the ventricular pacing pulses in accordance with a programmed pacing mode and controls delivery of the neural stimulation. The controller is programmed to deliver remodeling control therapy (RCT) by delivering ventricular pacing to pre-excite a ventricular myocardium region to mechanically unload that region during systole, and further is programmed to deliver anti-remodeling therapy (ART) by delivering neural stimulation to inhibit sympathetic nerve activity in conjunction with RCT. Other embodiments are provided herein.
