Abstract: An ultrasound diagnostic apparatus includes processing circuitry and a display. The processing circuitry is configured to concurrently obtain a plurality of cardiac function indexes for at least two or more cardiac chambers including a left ventricle and a right ventricle among cardiac chambers appearing on an apical 4-chamber moving image of a subject during one or more heartbeats, based on boundary positions of the cardiac chambers appearing on the apical 4-chamber moving image. The display displays at least one or more of the plurality of cardiac function indexes.
