Figure 3.

Isovolumic contraction time at baseline LV dysfunction (LVDys) and following pressure loading in dogs with LV dysfunction and preserved ejection fraction (left upper) and LV dysfunction with reduced ejection fraction (right upper) demonstrates similar extent of increases with pressure loading. Similarly, the isovolumic relaxation period at baseline LV dysfunction (LVDys) and following pressure loading in dogs with LV dysfunction and preserved ejection fraction (left lower) and LV dysfunction with reduced ejection fraction (right lower) demonstrates a similar degree of lengthening with pressure loading.
