Abstract

The invention provides a system and method for phase synchronization analysis of a cardiopulmonary system. The system and method are used for evaluating the synchronization degree of the heart rate and respiration, namely cardiopulmonary coupling strength. The system comprises an electrocardio signal collecting module, an electrocardio signal preprocessing module, an electrocardio R wave crest detection module, a respiration signal collecting module, a respiration signal preprocessing module, a respiration signal wave crest detection module and a phase synchronization analyzing module. The electrocardio signal collecting module is used for collecting electrocardio signals, the electrocardio R wave crest detection module detects an R wave crest by the adoption of an R wave detection algorithm based on wavelet transform, the respiration signal collecting module is used for collecting respiration signals, the respiration signal wave crest detection module is used for detecting a respiration wave crest point by the adoption of a threshold method, and the phase synchronization analyzing module is used for calculating cardiopulmonary synchronization time on the basis of a phase synchronization graph to serve as a quantitative index of the cardiopulmonary coupling strength.

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...
