特徴とする、超音波診断装置。 An ultrasonic diagnostic device that simultaneously displays an electrocardiogram and a pressure pulse wave as well as an electrocardiogram waveform has a peak detector for electrocardiogram waveforms, and data from each waveform buffer amplifier is sent to A via a multiplexer.
When the heart sound data is written to the buffer memory by the A/D converter, a short conversion clock for only the heart sound data is sent from the address controller to the A/D converter in synchronization with the electrocardiogram waveform peak detection signal, or similarly, only the heart sound data is sent to the multiplexer. An ultrasonic diagnostic apparatus characterized in that a switching period is long and buffer memory data is read out in synchronization with the peak detection signal during display.
