An ultrasonic medical monitoring device may include: at least one ultrasonic probe that scans a test subject to acquire an echo signal； a blood pressure measuring device that measures a blood pressure parameter of a peripheral artery of the test subject； a processor configured to receive the echo signal and process the echo signal to obtain a blood flow parameter, and to calculate a myocardial mechanic parameter that represents a synchronous coupling of a circulatory system of left ventricle-aorta-peripheral arteries circulation according to the blood flow parameter and the blood pressure parameter； and a display device that is coupled to the processor and displays the myocardial mechanic parameter.
