Three dimensional color-coded strain maps are shown at four times spaced evenly through systole. Average three dimensional color-coded strain from 10 normal left ventricles. Figure 2 shows the midwall normal strains, with the mean in red and one standard deviation line in blue. Evolution of strain throughout the average normal left ventricle. Midwall strain is plotted at 12 positions circumferentially and 6 longitudinally.
Different arrays illustrate different strain components.
The two patients without mechanical deficit had clinical evidence of reperfusion and no infarction. Strains in a heart with an acute transmural inferior infarct are shown in Figures 3 and 4. Strain rendering of a heart with inferior infarction. This figure is analogous to Figure 1. Evolution of strain throughout two hearts with inferior infarction.
