Abstract
An ultrasound diagnosis apparatus which performs ultrasonic diagnosis with respect of a fetal heart. An area change measurement section calculates an area of a specific heart chamber (left ventricle) in the fetal heart in frame units. Further, the area change measurement section generates a graph representing the area which is calculated in frame units. The maximum value and the minimum value are specified in the graph to thereby specify end-diastole and end-systole. Based on this information, a heart rate and a cardiac cycle with regard to the fetal heart are calculated. Further, an ejection fraction is also calculated from an end-diastolic area and an end-systolic area.
