Ultrasonic diagnostic apparatus and method of retrieving and displaying heart function test period

摘要

The present invention provides an ultrasonic diagnostic apparatus including a bio-signal analyzing section sequentially acquiring a bio-signal from a bio-signal acquiring section over a plurality of cycles to evaluate stability of a heart function in one cycle between particular signal waveforms of the bio-signal and one cycle between particular signal waveforms adjacent to the one cycle between the particular signal waveforms, selecting the one cycle between the particular signal waveforms and one cycle between the particular signal waveforms adjacent to the one cycle between the particular signal waveforms as a test period for the heart function based on the content of the evaluation, and associating the selected test period with a time phase of the bio-signal.

1. An ultrasonic diagnostic apparatus comprising:
an ultrasonic image producing section that transmits ultrasonic waves to an object with an ultrasonic probe and produces ultrasonic image data based on a ultrasonic reception signal; a heart function measuring and computing section that determines heart function measurement data using the ultrasonic reception signal; a bio-signal acquiring section that acquires a bio-signal periodically changing due to motions of a heart of the object; a display section that displays the ultrasonic image data, the heart function measurement data, and an image of the bio-signal, wherein the bio-signal includes an electrocardiogram; a control section that controls each of the sections; and a bio-signal analyzing section, communicatively connected to the bio-signal acquiring section, that:
detects a plurality of specific waves and obtains specific waves-specific waves intervals,evaluates irregularity of specific waves by a result obtained by judging whether a ratio of consecutive two or more specific waves-specific waves intervals is in a predetermined range, andsets non-conforming period or conforming period by the results of the evaluation.
