Abstract

The present invention provides a system and method for phase synchronization analysis of the cardiopulmonary system, which is used to evaluate the degree of synchronization between heart rate and respiration, that is, the cardiopulmonary coupling strength; the system includes an ECG signal acquisition module, an ECG signal preprocessing module, ECG signal R peak detection module, respiratory signal acquisition module, respiratory signal preprocessing module, respiratory signal peak detection module and phase synchronization analysis module; wherein, the ECG signal acquisition module collects ECG signals; the ECG signal R peak detection module adopts The R wave detection algorithm based on wavelet transform detects the R wave peak; the respiratory signal acquisition module collects the respiratory signal; the respiratory signal peak detection module uses the threshold method to detect the respiratory peak point; the phase synchronization analysis module calculates the cardiopulmonary synchronization time based on the phase synchronization diagram as the cardiopulmonary coupling strength quantitative indicators.

Description

technical field [0001] The present invention relates to a system and method for synchronous analysis of heart rate and respiration phase. Background technique [0002] The cardiovascular system and the respiratory system are regulated by nerves and body fluids, and work in their respective rhythms to maintain the normal life activities of the human body. But they are not independent and have no influence on each other, but cooperate closely to complete physiological functions together. [0003] Under the regulation and control of the central nervous system, breathing activity has its own exercise rhythm like heart activity, and the depth and frequency of this rhythm will change with the environment inside and outside the body. At the same time, rhythmic breathing is not only regulated by the central nervous system, but also reflexively regulated by incoming impulses from the respiratory organ itself and other organ receptors such as blood circulation, such as chemosensory r...
