The invention provides an ECG signal R wave detection method and device.This method includes: pre -processing the ECG signal of the collection target users; the pre -processing ECG signal after the first -order differential processing is smoothly processed to obtain the first -order differential smooth signal of the electrical signal; for each for each; for each each other;The first -order differential smooth signal of the electrical signal of the sampling cycle, obtain the maximum value of the first -order smooth signal with a rising rising along the differential threshold, and the minimum value of the first -order differential smooth signal of the first -level smooth signal at the preset drop along the downtime.; According to the maximum value of the first -order difference smooth signal and the minimum value of the first -order difference smooth signal, obtain the width of the target user to test R waves;Describe the waves of R waves to test.The present invention conducts a first -order difference polar value dynamic threshold judgment on the bilateral bilateral side of the R wave, looking for the R wave peak position with zero -level difference, and quickly and accurately realize the R -wave detection of ECG signals.
Description
technical field [0001] The invention relates to the technical field of data processing, in particular to a method and device for detecting an R wave of an electrocardiographic signal. Background technique [0002] Electrocardiograph (ECG) contains abundant physiological data of the human body in daily life activities such as rest and exercise. ECG signal QRS wave (Q, R, S represent the three logo positions of the ECG waveform) detection plays an important role in the continuous non-invasive multi-vital sign monitoring system. [0003] The noise usually mixed into the ECG signal includes baseline drift, DC offset, power frequency noise, impedance capacitive reactance changes caused by ECG electrode pads in contact with the human body, and motion myoelectric noise generated by limb movements. Among them, sports myoelectric noise changes with the way and intensity of human movement, and the frequency band is slightly higher than the baseline drift, at about 1-5 Hz, which is th...
