A method of detecting the vascular condition based on point fluctuation conduction characteristics of the heart and a device utilizing the same are disclosed in this patent. The method comprises: attaching flexible detection terminals firmly against the external skin adjacent to the heart or vascular walls; discretizing the detection area of the heart muscle or vascular walls into a plurality of preset detection points; through active emission of ultrasonic waves and continuous array reception of ultrasonic echoes carrying out multidimensional inversion of point fluctuations/point pulse waves using backend inversion; taking the multiple point fluctuations of the heart muscle as the multiple input signals of the vascular system and the multiple point pulse waves of a certain detection location of the blood vessel as the multiple output signals of the vascular system; identifying the vascular conduction characteristics by using digital signal processing methods; obtaining the conduction characteristics of a certain section of the blood vessel by decomposing the vascular conduction characteristics at different locations based on the cascade feature of the blood vessel; through feature extraction and feature comparison realizing the prediction and diagnosis of the vascular condition and the corresponding symptoms. The device comprises a plurality of flexible detection terminals with ultrasonic transceiving capability, a control module and a computing module, wherein the flexible detection terminal includes an ultrasonic transceiver probe array which is fixed on a flexible circuit board.
