Embodiment Construction

[0103]The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.

[0104] The modulation of breathing on the heart rate (respiratory sinus arrhythmia, RSA) is manifested as: when the human body performs inspiratory movement, the chest expands, and this activity excites the stretch receptors in the lungs in the smooth muscle layer of the bronchi and bronchioles, sending impulses and sending impulses to the heart rate. into the respiratory center. The center integrates the incoming information, inhibits the activity of the vagus nerve, and enhances the activity of the sympathetic nerve, thereby increasing the heart rate and blood pressure. After the blood pressure rises, the arterial baroreceptors located in the subadventitia of the carotid sinus and aortic arch are excited, and the impulse is sent to the center. After the center integrates the information of the inco...

Abstract

The invention provides a cardiopulmonary harmony series index evaluating method, device and system. The method includes the following steps that electrocardio signals, respiratory signals and motion signals of evaluated people are filtered, denoised and pretreated, a RR interval sequence is extracted from the electrocardio signals, and according to the RR interval sequence and the respiratory signals, a binary regression mathematical model is constructed; parameters in the binary regression mathematical model are transformed to a frequency domain to obtain a transformation matrix; the transformation matrix is analyzed to obtain a cardiopulmonary harmony series index; the cardiopulmonary harmony series index includes a cardiopulmonary harmony curve, a cardiopulmonary harmony degree, cardiopulmonary resonance frequency, a cardiopulmonary resonance factor, a cardiopulmonary harmony curve bandwidth and a cardiopulmonary resonance quality factor; and the cardiopulmonary harmony curve is used for representing the effect value of respiration on the modulation of the RR interval sequence at different frequency points in the frequency domain. By proposing the concept of the cardiopulmonaryharmony series index, the embodiment of the invention provides a method to obtain the cardiopulmonary harmony series index, and can provide the reliable digital measurement for the evaluation of a cardiopulmonary metabolism system.

Description

technical field [0001] The present application relates to the technical field of information processing, in particular, to a method, device and system for evaluating cardiopulmonary harmony series indexes. Background technique [0002] The human cardiopulmonary metabolic system provides nutrients to various organs and cells to ensure the normal operation of living organisms. The internationally recognized Respiration Sinus Arrhythmia (RSA) is a physiological mechanism for cardiopulmonary coordination to ensure efficient delivery of oxygen and nutrients and recovery of metabolites. A large number of studies have proved that the level of respiratory heart rate modulation (RSA) is directly related to the physiological and mental health of the human body, and represents the activity level of the parasympathetic nerve. In this way, quantitatively and accurately giving the evaluation index of respiratory heart rate modulation (RSA) has become a key technology and means for releva...
