Shortening AV delay may improve hemodynamics in pacemaker patients with diastolic MR; hypothesis-generating and leaves open confirmation in prospective trials.
Does AV sequential pacing with shortened AV delay improve cardiac output and PCWP in patients with intrinsic AV conduction and implanted DDD pacemakers?
Optimizing AV delay to eliminate diastolic mitral regurgitation improves cardiac output and reduces pulmonary capillary wedge pressure in pacemaker patients with intrinsic AV conduction.
