Embodiment Construction

[0043] The present invention is described in detail below in conjunction with accompanying drawing

[0044] The process of the present invention is as follows: first filter the collected electrocardiographic signal, then identify the R wave of the II-level lead electrocardiographic signal, and use the position of the R wave of the II-level lead signal as a reference for other multi-level conductors. The R wave of the ECG signal is identified, and then the Q wave and S wave of the multi-level lead signal are identified, so as to realize the QRS waveform identification of the multi-lead ECG signal.

[0045] The filtering process is described as follows: the collected ECG signal contains noise such as baseline drift noise, power frequency interference noise, and myoelectric interference noise. Baseline drift noise is low-frequency noise, power frequency interference noise and myoelectric interference noise are high-frequency noise. The present invention uses the fifth-order wavele...

Abstract

The invention relates to a multistage lead electrocardiograph signal QRS waveform identification method. The method includes the steps that firstly, collected electrocardiograph signals are filtered, R waves of the II-stage lead electrocardiograph signals are identified, the positions of the R waves of the II-stage lead electrocardiograph signals serve as reference, R waves of other stages of lead electrocardiograph signals are identified, then Q waves and S waves of the multistage lead electrocardiograph signals are identified, and therefore multistage lead electrocardiograph signal QRS waveform identification is achieved. The method has the advantages that a new method is proposed for wavelet transformation R wave identification and matching errors of the maximal value and the minimal value in a traditional maximal value-minimal value method can be avoided. The method is particularly suitable for electrocardiograph signal QRS waveform identification.

Description

technical field [0001] The invention relates to a method for identifying QRS waveforms of electrocardiographic signals, in particular to a method for identifying QRS waveforms of multilevel lead electrocardiographic signals based on wavelet transform. Background technique [0002] Due to the aggravation of the aging population in our country and the unbalanced distribution of existing medical resources, the medical and health field is becoming more and more important in our country. Among them, cardiovascular disease is an important disease that endangers the health of modern people, and the prevention and treatment of cardiovascular disease has become particularly important. The recognition of ECG signal waveform is an important link in the treatment of cardiovascular diseases, and its theoretical research needs to provide a high accuracy rate. The steps of ECG waveform identification often start with QRS waveform identification. [0003] In the traditional ECG signal det...
