Embodiment Construction

[0025] Such as figure 1 shown. The forward pressure wave is caused by the impact of the left heart on the aortic valve and the vessel wall; the forward pressure wave starts from the root of the aorta and propagates along the arterial tree to the peripheral arteries, under the joint action of arterial branches and peripheral resistance arteries , to generate a reflected wave opposite to the direction of the forward pressure wave; after the ventricular ejection ends and the aortic valve closes, the elastic potential energy stored in the aorta is released to generate a dicrotic wave. Forward pressure wave, reflected wave and dicrotic wave are superimposed on each other, and due to the difference in heart function, arterial structure and surrounding tissue and organ conditions, a variety of pulse wave forms are formed.

[0026] In short, the forward pressure wave generated when the heart ejects blood propagates along the arterial tree, and the main wave of the radial artery pulse...

Abstract

The invention discloses a method for obtaining the pulse wave velocity of aorta by using pulse wave of radial artery, relating to the field of cardiovascular medicines in biomedicine. In the invention, based on the waveform at one point of radial artery, the pulse wave transit time of the aorta can be analyzed and obtained, further, the pulse wave velocity of the aorta can be calculated, and the calculation formula is as follows: the pulse wave velocity of the aorta (aoPWV)is equal to a result that the time difference (delta t) between the main wave and the reflected wave of the pulse wave ofthe radial artery is divided by two times of the length of the aorta, that is, aoPWV=2L/delta t; in the invention, the transmit theory of the pulse wave is firstly applied in the calculation of the PWV, two acquisition points are simplified to form one point, the acquisition position is changed to the radial artery from carotid and femoral artery, signal acquisition difficulty is decreased, the testing procedure is simplified, and no hazard exists. A pulse measuring device in the invention is a pulse clip fixed-pulse sensor, so that the acquisition of the pulse wave of the radial artery is easier; besides, the operation is convenient, and the requirement for operators is low.

Description

technical field [0001] The invention relates to the field of cardiovascular medicine in biomedicine, in particular to a method for obtaining aortic pulse wave velocity by using radial artery pulse wave. Background technique [0002] Cardiovascular disease is the leading cause of death worldwide. About 17.1 million people die of cardiovascular disease every year in the world, accounting for 29% of the total death (World Health Organization fact report No. 317 in September 2009). It is estimated that 3 million people die from cardiovascular disease every year in my country, and 1 out of 3 deaths is caused by cardiovascular disease ("China Cardiovascular Disease Report 2007"). Cardiovascular disease has become a major public health problem threatening human health in the 21st century. [0003] The essence of cardiovascular disease is the change of the overall structure and function of arteries (including aorta) caused by arteriosclerosis. The change of arterial stiffness is ...
