Problems solved by technology

Tens of thousands of people in many countries suffer from various degrees of cardiovascular diseases. In the diagnosis and treatment of heart disease, the most widely used and most important detection technology is electrocardiogram, but a single analysis of electrocardiographic signals or respiratory signals , the accuracy and stability of the analysis results will be seriously affected by sequence instability. How to realize the analysis of cardiopulmonary coupling relationship and study cardiovascular diseases from multiple perspectives has become a hot topic in current research

Embodiment Construction

[0116] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0117] S1: collect the ECG signal and respiratory signal of the human body, form the ECG signal sequence and the respiratory signal sequence, and preprocess the collected ECG signal sequence and respiratory signal sequence respectively.

[0118] In the S1 step, the ECG signal sequence and the respiratory signal sequence of the human body are collected, including:

[0119] Fix the ECG electrode sheet on the skin of the human body, the ECG electrode sheet continuously acquires the ECG signal of the human body, and transmits the ECG signal to the ECG sensor, and the ECG signal sequence received by the ECG sensor is d(t); There is a high-pass filter inside the ECG sensor, which allows the ECG sensor to receive signals whose frequency is higher than the cutoff frequency f t ECG signal, the cutoff frequency f t The calcul...

Abstract

The invention relates to the technical field of cardiopulmonary coupling relationship analysis, and discloses an information gain-based cardiopulmonary coupling relationship analysis method, which comprises the following steps: acquiring an electrocardiosignal and a respiratory signal of a human body to form an electrocardiosignal sequence and a respiratory signal sequence, and respectively preprocessing the acquired electrocardiosignal sequence and respiratory signal sequence; filtering the pre-processed electrocardiosignal sequence and the pre-processed respiration signal sequence through a variable-step-size self-adaptive filtering algorithm; performing empirical mode decomposition on the filtered electrocardiosignal sequence and respiratory signal sequence; and carrying out information gain calculation on the decomposed electrocardiosignal sequence and respiratory signal sequence. According to the method, empirical mode decomposition is conducted on an electrocardiosignal sequence and a respiratory signal sequence, information gain calculation is conducted on the decomposed signal sequences, the smaller the information gain is, the stronger the cardiopulmonary coupling relation is, and therefore cardiopulmonary coupling relation analysis is achieved.

Description

technical field [0001] The invention relates to the technical field of cardiopulmonary coupling relationship analysis, in particular to an information gain-based cardiopulmonary coupling relationship analysis method. Background technique [0002] With the increasing pressure of people's life and work, the rate of cardiovascular diseases has also shown a continuous upward trend year by year, and heart diseases have become the main cause of death. Tens of thousands of people in many countries suffer from various degrees of cardiovascular diseases. In the diagnosis and treatment of heart disease, the most widely used and most important detection technology is electrocardiogram, but a single analysis of electrocardiographic signals or respiratory signals , the accuracy and stability of the analysis results will be seriously affected by sequence instability. How to realize the analysis of the cardiopulmonary coupling relationship and study cardiovascular diseases from multiple pe...
