Description

technical field [0001] The invention belongs to the field of electronic medical instruments. It is a method and device for evaluating microvascular function by automatically analyzing and discriminating the acquired volume pulse waveform through computer technology, signal acquisition technology, digital signal processing technology, etc. Background technique [0002] The volume pulse wave is the pulsatile change in the blood volume of the microvessels when the arterial blood flows through the microvessels such as arterioles, capillaries and venules in the peripheral blood vessels under the beating of the heart. Since the volume pulse wave is the blood flow volume pulse of the microvascular in the microcirculation, it is located at the distal end of the arterial system, so the volume pulse wave contains rich information on the microcirculation, as well as the closely related information on the microvascular function. [0003] In recent years, many scientific researchers at ...
