Method and device for identifying artifact electrocardiograph waveforms

Abstract

The invention discloses a method and a device for identifying artifact electrocardiograph waveforms. The method comprises the following steps of: reading the original electrocardiograph waveform data; filtering the middle baseline drift and high-frequency noise in the original electrocardiograph waveform data, and then obtaining the preprocessed electrocardiograph waveform data; estimating the abnormal electrocardiograph waveform data of the preprocessed electrocardiograph waveform data to obtain the normal electrocardiograph waveform data; obtaining the data corresponding to a section of continuous low-error electrocardiograph waveform in the normal electrocardiograph waveform data, extracting the electrocardiograph waveform data corresponding to an RR period from the data corresponding to the continuous low-error electrocardiograph waveform, and adopting the data as the electrocardiograph template data; adopting the electrocardiograph waveform data, which corresponds to the RR period in the normal electrocardiograph waveform data of which residual energy is larger than the pre-set multiple of the residual energy of the electrocardiograph template data, as the artifact electrocardiograph waveform data. The method can quickly identify the artifact electrocardiograph waveforms. In addition, the invention further provides a device for identifying artifact electrocardiograph waveforms.

Description

【Technical field】 [0001] The invention relates to the technical field of electrocardiographic waveform identification, in particular to a method and device for identifying false electrocardiographic waveforms. 【Background technique】 [0002] At present, the dynamic electrocardiogram automatic recognition technology develops very rapidly, but there are still many factors affecting the correct recognition of the dynamic electrocardiogram, and the artifact is one of them. The existence of artifacts has brought many difficulties to the automatic analysis of dynamic electrocardiogram by computer. The ECG waveform with artifacts is the ECG waveform with artifacts; the automatic identification of the ECG waveforms in the ECG waveforms is the difficulty that the dynamic ECG automatic analysis technology needs to overcome. [0003] At present, there are mainly non-linear methods proposed by domestic and foreign scholars for the identification of false ECG waveforms in ECG, such as s...

AI Technical Summary

Problems solved by technology

However, some of these methods need to process a large amount of data, and the processing time is too long to be acceptable, while some are not suitable for single-lead ECG signals, and their applications are not very wide

Therefore, the identification of false ECG waveforms at this stage mostly stays at the level of manual identification
