Cardiopulmonary Coupling Analysis Method Based on Single Lead ECG

Abstract

A cardiopulmonary coupling analysis method based on single lead ECG includes the steps of extracting an RR inter-phase sequence and an EDR signal from body surface single-lead ECG signals, eliminating the noise components of the EDR signal according to the relevance between the RR inter-phase sequence and the EDR signal by means of a self-adaptive filter with the RR inter-phase sequence as the reference input signal of the self-adaptive filter and the EDR signal as the ideal signal of the self-adaptive filter to obtain an enhanced type EDR signal, conducting experience pattern decomposing on the RR inter-phase sequence and the enhanced type EDR signal to obtain a plurality of intrinsic mode functions of the RR inter-phase sequence and a plurality of intrinsic mode functions of the enhanced type EDR signal, and selecting the intrinsic mode function, corresponding to a preset frequency band, of the RR inter-phase sequence and the intrinsic mode function, corresponding to the preset frequency band, of the enhanced type EDR signal for cardiopulmonary coupling analysis to obtain a coupling result.

Description

technical field [0001] The invention relates to a physiological parameter analysis method, in particular to a cardiopulmonary coupling analysis method based on a single-lead ECG. Background technique [0002] Cardiopulmonary coupling (cardiopulmonary coupling), also known as cardiorespiratory interaction, refers to the internal coordination mechanism and role between the cardiovascular system and the respiratory system, and its research involves a wide range of physiological, pathological and clinical application fields. The cardiopulmonary coupling phenomenon can be used to obtain physiological and pathological information related to the health status of the body, such as evaluating the function of the autonomic nervous system through cardiopulmonary coupling analysis, quantitatively evaluating sleep quality, and detecting sleep-breathing events. Through the physiological phenomenon of cardiopulmonary coupling, it can also regulate and intervene in the health state of the b...
