Specifically, volume loading in a canine model of normal and reduced LV function resulted in a lower IMP by prolonging LVET (5).
Clinically, LV volume overload produced by chronic aortic regurgitation (AR) results in a prolonged LVET (7-11) and may theoretically reduce IMP.
Transaortic Doppler was used to obtain LVET, which was measured from the onset to the end of the aortic velocity spectrum.
The ICT was determined by subtracting LVET and IRT from "a".
The LVET in the LVD group was shorter than in normals and in both AR groups (p<0.
