Embodiment Construction

[0038] Such as figure 1 As shown, the present invention discloses a system for acquiring and processing ECG signal data. The system for acquiring and processing ECG signal data includes:

[0039] Electrode and lead wire unit 01, the electrode and lead wire unit 01 is used to collect the ECG signal of the human body, the output end of the electrode and lead wire unit 01 is connected to the input end of the pre-low pass filter 21.

[0040] The electrode and lead wire unit 01 is connected to the human body, and outputs physiological signals to the signal acquisition unit 02 . The electrode and lead wire unit 01 are generally conductors such as limb clips, chest guide suction balls, electrode sheets, etc., which are in close contact with the human body to obtain human physiological signals. In the present invention, the electrode and lead wire unit 01 is used to obtain human body signals ECG.

[0041] The electrocardiographic signal data acquisition and processing system also in...

Abstract

The invention provides an electrocardiosignal data acquisition and processing method and system. The electrocardiosignal data acquisition and processing system comprises a data processing unit which comprises a data analysis unit. The data analysis unit comprises an RR interphase preprocessing unit and an instantaneous feature extraction unit. The RR interphase preprocessing unit is used for preprocessing an RR interphase sequence, so that a signal bandwidth of an RR interphase is enabled to fall in a frequency bandwidth requested by the best amplitude frequency features of the Hilbert transform. The instantaneous feature extraction unit is used for extracting instantaneous amplitude features and instantaneous frequency features of the RR interphase sequence. The electrocardiosignal data acquisition and processing system has the advantages that through acquisition and processing of the electrocardiosignals, complexity of data analysis is reduced, and amount of calculation is decreased; the system is simple in design, low in cost and convenient to apply.

Description

technical field [0001] The invention relates to the field of data processing, in particular to a method and system for acquiring and processing ECG signal data. Background technique [0002] Sleep quality directly affects people's daily life. Sleep apnea syndrome is a very common disease. It occurs in 2%-4% of adults, and most of them are Obstructive Sleep Apnea (Obstructive Sleep Apnea, referred to as OSA). Obstructive sleep apnea syndrome can cause a variety of arrhythmias and increase the morbidity and mortality of cardiovascular events. [0003] The acquisition of traditional sleep apnea event information relies on polysomnography technology, which needs to be carried out in a professional sleep laboratory and under the supervision of medical staff. The polysomnography has a total of 11 leads, which can form various synchronous graphics and continuously record the micro-electrical changes in the patient's EEG, eye movement, ECG, blood oxygen saturation, etc. after adju...
