Electrocardiosignal anomaly detection method, system and device and storage medium

Abstract

The invention discloses an electrocardiosignal anomaly detection method, system and device and a storage medium. The electrocardiosignal anomaly detection method comprises the steps of obtaining first data; preprocessing the first data to generate second data; obtaining a preset number of samples from the second data as first samples; inputting the first sample into the grid model for training, and generating an encoder; performing feature processing and dimension reduction on the first data through an encoder to generate a second sample; and according to the second sample, generating an electrocardiosignal detection result through a hidden Markov model. According to the method, the encoder is obtained by training the grid model integrated by the bidirectional circulation gating unit layer and the attention layer, the data processing capacity of the encoder is improved, and the encoder can extract more detail features from original electrocardiosignal data; the hidden Markov model with the Watson hybrid model as the emission density is adopted to recognize the sample, and the accuracy and comprehensiveness of the electrocardiosignal detection result are improved.

Description

technical field [0001] The present application relates to the technical field of detection, in particular to a method, system, device and storage medium for abnormal detection of ECG signals. Background technique [0002] The traditional detection of ECG abnormality usually requires doctors with rich clinical experience to read the images manually with the naked eye. The degree of automation is low, and there are problems such as low detection efficiency and misdiagnosis due to doctor fatigue. Most of the existing ECG automatic detection methods use neural network models. The neural network model is a supervised classification method, which requires a lot of manpower to mark a large number of labeled ECG data, and the accuracy is not high in the case of small sample data. [0003] At present, some ECG signal abnormality detection methods use unsupervised deep models or data modeling. [0004] Among them, the network layer of the self-encoding hidden layer of the unsupervis...
