Abstract

The invention discloses a method for quantum resonance spectrometer (QRS) wave group extraction. The method comprises the steps of obtaining original signals; performing structural elementary processing on the original signals; applying morphology to operate the signals having undergone structural elementary processing to obtain characteristic signals of the original signals; and extracting QRS wave groups from the characteristic signals. The invention further discloses a device for QRS wave group extraction. According to the method and device for QRS wave group extraction, a QRS wave group is extracted from originally collected electrocardiosignals, the calculated amount is small, and extracting accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of medical signal processing, in particular to a QRS wave group extraction method and device. Background technique [0002] Currently monitoring human health, the method of extracting QRS complexes (reflecting the electrical activation process of left and right ventricles) in ECG signals through wearable devices is based on two algorithms. The first is PT, Pan-Tompkins algorithm, which mainly passes ECG and Electrocardiograph ECG signals through band-pass filter, differencer and square module, and is based on the first-order differential Hilbert transform method. In this method, The threshold is variable and free from human interference; the second is the FDD algorithm, which mainly uses a FIR bandpass filter, and the coefficients of the filter are related to the order of the fraction. The above two extraction methods are both detection methods based on first-order differential signals, and other subsequent...
