An ultrasonic medical monitoring device may include: at least one ultrasonic probe attached to a body surface of a subject to scan the body surface and acquire an echo signal； a blood pressure measuring module to measure a blood pressure parameter of the subject； a processing module to receive the echo signal and process the echo signal into a blood flow parameter, the processing module being further configured to calculate a myocardial mechanic parameter according to the blood flow parameter and the blood pressure parameter； and a display module coupled to the processing module to display the blood pressure parameter, the blood flow parameter, and the myocardial mechanic parameter. The present device and method acquire the blood pressure parameter and the blood flow parameter using ultrasound and a blood pressure synchronous detection technique, and the myocardial mechanics parameters such as the systolic maximum elastance are calculated by a computer.
