Abstract
A method and apparatus for determining the baroreflex sensitivity in a chronic heart failure patient and a method for chronic heart therapy evaluation. The method including providing a series of pacing stimuli to the heart of a chronic heart failure patient and measuring the change in pulse pressure and the change in cycle length incident to each pacing series. The changes being plotted to produce a line indicative of baroreflex sensitivity. The apparatus including a pacemaker having sensors for monitoring both cycle length and pulse pressure wherein the sensors may be integral or separate from the pacemaker. The method for evaluating chronic heart failure therapies including administering a series of therapies and evaluating each therapy based on the resultant increase of the patient's baroreflex sensitivity.
