Abstract

The invention discloses a cardiopulmonary coupling analysis method based on a single-channel ECG signal. The cardiopulmonary coupling analysis method specifically comprises the steps that an RR interval sequence and an EDR signal are extracted from a body surface single-lead ECG signal; interpolating the RR interval sequence and the EDR sequence to the same sampling rate by using cubic spline interpolation; calculating an autocorrelation function and a cross-correlation function of the RR interval sequence and the EDR sequence; fourier transform is carried out to respectively obtain self-correlation power and cross-correlation power; calculating a cardiopulmonary coupling result through the cross-correlation power to obtain a cardiopulmonary coupling map; and analyzing the sleep quality according to the cardiopulmonary coupling atlas. The cardiopulmonary coupling result is calculated through the cross-correlation power, then the cardiopulmonary coupling map is obtained to analyze the sleep quality, the sleep quality analysis accuracy is improved, the method can be used for home detection to reflect the real sleep condition, accurate judgment on the sleep quality of a user is facilitated, and making of a personalized conditioning scheme is facilitated.

Description

technical field [0001] The invention relates to the technical field of medical health detection, in particular to a cardiopulmonary coupling analysis method based on a single-channel ECG signal. Background technique [0002] The discovery of brain waves in the last century made sleep researchers very excited, and they defined brain waves as the core signal for evaluating sleep. Later, they added oculoelectricity, myoelectricity, breathing, ECG, blood oxygen and other physiological signals. Collected to form the polysomnography (PSG) currently used in hospitals. Although polysomnography has its advantages, it also has many disadvantages at the same time. For example, the subjects need to connect various wires on their bodies and sleep overnight in the sleep laboratory of the hospital. Such environments and conditions often cannot reflect the real sleep of the subjects; another big problem is that experienced technicians must spend several hours manually identifying the chara...
