A region of interest is set at a thin layer on the inside of the left ventricular wall for ecocardiographical apical long-axis tomographic images obtained while at rest, and the strain rate of the set region of interest is calculated. The value of a discriminant function is determined on the basis of a plurality of strain rates of an intermediate portion of the systolic phase. Ischemic heart disease is then diagnosed according to the value of the discriminant function. |
