Problems solved by technology

[0004] Related QRS complex detection technology implementations include differential operator-based analysis methods, wavelet decomposition-based analysis methods, neural network-based analysis methods, etc. However, related methods for detecting QRS complexes are usually based on a certain channel However, the ECG signal is easily interfered by noise, which will cause the signal quality of a channel’s ECG signal to decline, which will affect the accuracy of QRS wave group detection.

Abstract

The invention provides a QRS wave group detection method and device. The method comprises that a multi-lead electrocardio signal to be processed is obtained; first characteristic information is extracted from the multi-lead electrocardio signal; and a QRS wave group area of the multi-lead electrocardio signal is determined according to a pre-trained QRS wave group detection model and the first characteristic information. Thus, the QRS wave group area is determined more accurately, and accurate basis is provided for subsequent analysis based on the QRS wave group area.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a method and device for detecting QRS complexes. Background technique [0002] Electrocardiogram has been used in clinical practice for a century. As an independent clinical examination and diagnosis discipline, it has formed its own system. Treatment and monitoring provide objective indicators. [0003] With the development of science and technology, the use of computer intelligence to assist the analysis and diagnosis of ECG has been widely used in clinical medicine. The electrocardiogram is composed of periodic waveforms, such as P wave, QRS wave group, T wave, etc. Among them, the QRS wave group is the most prominent part of the electrocardiogram, which reflects the electrical behavior of the heart during ventricular contraction, and the QRS wave group The occurrence and shape of the group give the current state information of the heart, so in the automatic detection and a...
