A method of analyzing regional ventricular function utilizing centerline method capable of producing sufficiently natural results in the vicinity of the apex. The method includes the step of drawing a line between the end-diastolic and end-systolic contours, which is converting to an intersection of the end-systolic contour and a major axis joining the apex of the end-diastolic contour and a midpoint of an aortic valve portion of the end-diastolic contour, whenever a line to be drawn between the end-diastolic and end-systolic contour is going to intersect with the major axis. In the method, all the lines to be drawn between the end-diastolic and end-systolic contours are drawn sequentially in a first direction from one end of an aortic valve portion toward an apex for one half of the end-diastolic contour, and in a second direction from another end of the aortic valve portion toward the apex, which is opposite to the first direction, for other half of the end-diastolic contour.
