A method and system for measuring and optimizing pulse r-r interval during sleep

Abstract

The invention relates to a pulse R-R interval measurement and optimization method and system during a sleeping period. Through non-contact and high-portability equipment and a method with high detection accuracy, the sleeping condition of a testee is detected in real time; only through detecting the pulse signal, the extraction of the accurate R-R interval value can be realized by using various algorithms; the pulse value is subjected to primary screening through the covariance matching of the pulse peak value, and then, the primary R-R interval value is obtained; then, through an AR model, the bizarre primary R-R interval value is subjected to second screening, the effect of the existing R-R interval value collected by using the PSG is achieved; the requirements of a user to perform R-R interval optimization in a daily life mode such as home staying or traveling can be met; the time and money consumption is reduced.

Description

technical field [0001] The present invention relates to an R-R interval optimization technology applicable to heart rate variability in daily life environment, in particular to a non-contact way to monitor breathing, pulse and other vital signs during sleep to optimize the R-R interval Pulse R-R interval measurement and optimization method and system during sleep. Background technique [0002] According to the "China Cardiovascular Disease Report (2015)", it is estimated that there are currently 290 million cardiovascular disease patients in China, and 3.5 million people die of cardiovascular disease every year. With the improvement of living standards, the acceleration of the pace of life and the arrival of the global aging society, the morbidity and mortality of heart disease will increase. It can be seen that heart disease has become one of the main diseases threatening human beings. Modern medical research has shown that obtaining continuous and accurate R-R intervals f...
