Abstract

The invention provides an electrocardiosignal R peak detection method based on waveform characteristic matching. The method utilizes waveform characteristic matching to identify R peak of electrocardiosignal, the characteristic matching method takes difference vector between points as basic characteristic, the basic characteristic has translational invariance and rotational invariance and can overcome influence of baseline drift of electrocardiosignal signal; meanwhile, logarithm polar coordinate transformation is carried out on the difference vector and partition is carried out to measure similarity of wave form, the measurement is sensitive to the adjacent morphological characteristic, can capture global outline information of wave form and has robustness to wave form ripple; besides, influence of interference signal can be eliminated by setting proper threshold, and further accurate identification and detection on R peak of electrocardiosignal are realized. The invention is applied to related electrocardiogram analyser, accurate identification on R peak of electrocardiosignal can be realized, thus being beneficial to improving detection and analysis capability of electrocardiogram analysis equipment.

Description

technical field

[0001] The invention relates to the technical field of automatic detection and analysis of electrocardiographic signals, in particular to an electrocardiographic signal R-peak detection method for feature extraction and matching of electrocardiographic signals. Background technique

[0002] Electrocardiogram (ECG for short) means that in each cardiac cycle, the heart is excited successively by the pacemaker, atria, and ventricles. changing graphics. The electrocardiogram is an objective indicator of the occurrence, propagation and recovery process of cardiac excitement. The QRS complex wave is an important feature of the ECG signal, and it is also the most basic problem in the detection of the ECG signal. It is not only the most important basis for diagnosing arrhythmia, but also other details of the ECG signal can only be analyzed after the QRS complex wave is determined. , for more information. If the QRS complex wave detection is inaccurate, it will gre...
