Abstract

The application provides an irregular pulse rate identification method. The irregular pulse rate identification method comprises the following steps: collecting a first physiological signal of a testee, wherein the first physiological signal at least includes pulse information; collecting a second physiological signal of the same testee, wherein the second physiological signal at least includes respiration information; obtaining pulse feature information according to the first physiological signal; obtaining respiration feature information according to the second physiological signal; filtering the first physiological signal according to the relationship between the respiration feature information and the pulse feature information, to filter off interference generated by respiration in thefirst physiological signal to obtain a filtered pulse wave signal; and identifying fluctuation rhythm information of a pulse wave according to the filtered pulse wave signal. The application furtherdiscloses a monitor. The irregular pulse rate identification method can filter off the influence of respiration on the pulse through adaptive filtering, and the irregular pulse rate identification accuracy is high.

Description

technical field [0001] The application relates to the field of medical monitoring, in particular to a monitor and an irregular pulse rate identification method thereof. Background technique [0002] The pulse is the palpable arterial pulse on the surface of the human body. The human circulatory system is composed of the heart, blood vessels, and blood, and is responsible for the transportation of oxygen, carbon dioxide, nutrients and waste. Blood is squeezed by the heart's left ventricle into the aorta, which then travels to arteries throughout the body. Arteries are tubes formed by elastic connective tissue and muscle. When a large amount of blood enters the artery, the pressure of the artery increases and the diameter of the artery expands, and the artery can feel the expansion at the shallower part of the body surface, which is the so-called pulse. Pulse rate is the pulse rate. The pulse rate of normal people is regular, there will be no phenomenon of different pulse ...
