Provided is an ultrasound diagnostic device, wherein, when a manipulation operation is inputted into a manipulation input unit, after a freeze or during a cine-play, which instructs a change of a D-mode image: an image control unit, according to the content of the manipulation input, varies a partial range of Doppler spectrum data upon a temporal axis, generates a new D-mode image and trace waveform, and changes a heart rate interval which the D-mode image which is displayed in a display apparatus represents; a heart rate interval selection unit detects, on the basis of the newly generated trace waveform, a plurality of heart rate intervals which the post-change D-mode image which is displayed in the display apparatus represents, and selects anew, on the basis of a prescribed selection reference, one or more heart rate intervals as heart rate intervals to be measured; and a measurement unit measures a prescribed diagnostic parameter on the basis of the newly generated trace waveform which is included in the newly selected heart rate interval to be measured. |
