Abstract

The invention discloses a method for processing and tracking heart rate and respiration rate signals. The method comprises the steps of signal processing, wherein an acceleration sensor is used for collecting heart rate and respiration rate acceleration original signals, and a wavelet method is adopted for removing noise signals to obtain denoised signals of the heart rate and the respiration rate; signal separating, wherein based on the denoised signals of the heart rate and the respiration rate, a signal smoothing method is adopted for obtaining respiration rate signals, and then a signal model is adopted for removing the respiration rate signals from the denoised signals of the heart rate and the respiration rate in real time to obtain heart rate signals; signal tracking estimation, wherein the signal tracking estimation step is used for tracking the respiration rate signals and the heart rate signals, instant respiration rate signals and instant heart rate signals are obtained within the set time period, and signal forecasting is carried out under the circumstance of signal loss.

Description

technical field [0001] The invention relates to the field of signal processing, in particular to a heart rate and respiration rate signal processing and tracking method and system thereof. Background technique [0002] Heart rate (heart rate) is of great significance to measure the health of a person's heart. It refers to the number of heart beats per unit time and is a physiological parameter for routine clinical diagnosis. Resting heart rate is usually measured, which refers to the number of heartbeats per minute when a person is awake and inactive. An increase in resting heart rate can lead to a shortened lifespan. It has been proved epidemiologically that elevated resting heart rate increases mortality, especially in patients with cardiovascular disease. In recent years, more and more medical research results have proved that increased resting heart rate can increase the morbidity and mortality of cardiovascular diseases, thus causing serious harm to health.
