In plural types of stress echocardiographies, every time a single type of stress or plural types of stresses are applied to a site in plural examination stages for the respective types, a data acquiring part transmits ultrasonic waves to a subject of a data acquisition target, and when reflected waves are received, values of plural types of parameters signifying the state of the site of the subject are obtained. Subsequently, when receiving a request to browse the examination results by designation of the type of stress echocardiography through an operation part, a display controller reads out, from the storage, the values of the parameters of the stress echocardiography of the designated type and displays a list of the values of the parameters on a graphic with one item as the types of the parameters and the other item as the respective examination stages of the designated stress examination.
