Abstract

The invention provides a heart rate measuring method and a heart rate measuring device based on the bioelectrical impedance technology. According to the heart rate measuring method, the bioelectrical impedance technology is adopted, specifically, an electrical impedance signal of the radial artery of the arm of a tested person is collected, then analog-digital conversion is carried out on the signal, thus an electrical impedance digital signal is obtained, and then the heart rate and heart rate variability characters are extracted from the electrical impedance digital signal. The heart rate measuring method has the characteristics of being simple and feasible, and being low in price and easy and convenient to operate, the heart rate data can be rapidly and accurately collected and analyzed, and the measurement for the tested person is realized.

Description

technical field [0001] The present invention relates to the technical field of medical monitoring, and more specifically, to a method and device for measuring heart rate based on bioelectrical impedance technology. Background technique [0002] At present, the main methods for measuring and extracting clinical heart rate and related features are measuring ECG electrical signals, PPG photoelectric signals, and pulse pressure signals. Traditional ECG measurement methods require the subject to be in a resting state, while photoelectric and other measurement methods, as indirect approximate measurement methods, are susceptible to environmental interference such as external light sources, so they cannot quickly and accurately collect and analyze heart rate-related data. [0003] Bioelectrical impedance measurement technology is a detection technology that utilizes the electrical characteristics and changes of biological tissues and organs to extract biomedical information related...
