Abstract

The invention provides an electrocardiosignal feature point detecting method and device. The electrocardiosignal feature point detecting method comprises the steps that signal point pair features of all electrocardiosignal feature points in a sample set are extracted, and the signal point pair features of all electrocardiosignal testing points in a testing set are extracted; a mode recognition algorithm is utilized to train the extracted signal point pair features in the sample set to obtain an electrocardiosignal feature classification model; the electrocardiosignal feature classification model is utilized to classify the signal point pair features of all the electrocardiosignal testing points so as to obtain classification results of the signal point pair features of all the electrocardiosignal testing points, and the classification results serve as feature point detecting results of the electrocardiosignal testing points. The electrocardiosignal feature point detecting method can detect electrocardiosignal feature points in real time and is simple to achieve and higher in detecting sensitivity and accuracy rate.

Description

technical field [0001] The invention relates to the technical field of electrocardiographic information processing, in particular to a method and device for detecting feature points of electrocardiographic signals. Background technique [0002] ECG (electrocardiogram, referred to as ECG) reflects the electrical activity process of heart excitation, which has important reference value for the basic function and pathological research of the heart. [0003] At present, the detection methods of feature points (P wave peak and its boundary, QRS wave, T wave peak and its boundary) of general ECG signals can be divided into: 1. Use the base expansion method for feature point detection; 2. Use adaptive filtering 3. Fitting the ECG signal using an ECG signal waveform model (such as a Gaussian model), and obtaining the positions of the P wave, T wave and QRS wave according to the fitting result. [0004] The base expansion method is used for feature point detection. The base expansio...
