Abstract:
1. A cardiac device, comprising: a pulse generator for outputting vasoactive stimulation pulses, wherein the pulse generator is connectable to a vasoactive stimulation electrode disposed in proximity to a coronary artery; a sensing amplifier for sensing cardiac electrical activity; an impedance sensor for measuring cardiac blood flow; a controller programmed to intermittently switch between a normal mode in which no vasoactive stimulation pulses are delivered or a vasodilation mode in which vasoactive stimulation pulses are delivered in a manner that causes vasodilation of the coronary artery; and, wherein the controller is further programmed to deliver vasoactive stimulation pulses in the vasodilation mode such that the delivery of vasoactive stimulation pulses is timed to occur coincidentally with mechanical ventricular diastole as determined from the measured cardiac blood flow.
