Abstract
A cardiac rhythm management device includes a dual chamber pacemaker especially designed for treating congestive heart failure. The device incorporates a programmed microcontroller which is operative to adjust the pacing mode-AV delay of the pacemaker so as to achieve optimum hemodynamic performance. Atrial cycle lengths measured during transient (immediate) time intervals following a change in the mode-AV delay are signal processed and a determination can then be made as to which particular configuration yields optimum performance.
