Figure 2 Strain rate tracings at rest (solid line) and during dobutamine stimulation (dotted line) for one cardiac cycle of a hypokinetic segment at rest, shown to be viable by ¹⁸FDG PET. There is an increase in the peak systolic strain rate from 1.1 1/s at rest to 2.0 l/s during dobutamine stimulation.
