Problems solved by technology

[0004] However, the P wave or f wave in the ECG signal is a weak signal, and its waveform characteristics are difficult to detect
Moreover, many non-AF types of abnormal rhythms (such as tachycardia, bradycardia, arrhythmia, etc.) show characteristics similar to AF, and if based on conventional ECG signal classification methods, erroneous identification results may occur
[0005] Therefore, the ECG signal classification method in the prior art has the problem of wrong classification of atrial fibrillation

Abstract

The invention relates to a method, a device, electronic equipment and a storage medium for electrocardiogram signal detection and classification. The method comprises the following steps of: extracting a signal waveform from an electrocardiogram signal; acquiring a morphological characteristic and a deep characteristic of the signal waveform, wherein the morphological characteristic comprises anyone of a TR wave amplitude difference characteristic, a PR wave quantity ratio characteristic, an ST wave band characteristic and a P wave variation characteristic, and the deep characteristic comprises a depth characteristic and a hierarchy characteristic; inputting the morphological characteristic and the deep characteristic into a classifier; and acquiring a classification result output by theclassifier so as to obtain the signal type of the electrocardiogram signal, wherein the classification result is a result that the classifier performs classification according to the morphological characteristic and the deep characteristic, and the signal type comprises an atrial fibrillation rhythm, a non-atrial fibrillation abnormal rhythm, a normal sinus rhythm and noise. The method can accurately identify various types of abnormal rhythms, avoids the situation that abnormal rhythms of non-atrial fibrillation types such as tachycardia, bradycardia and arrhythmia are classified into atrial fibrillation types in error, and improves the accuracy of classification of electrocardiogram signals.

Description

technical field [0001] The present application relates to the field of medical devices and medical products, in particular to a method, device, electronic equipment and storage medium for detecting and classifying electrocardiographic signals. Background technique [0002] Atrial fibrillation (AF), referred to as atrial fibrillation, is the most common clinical arrhythmia disease, which is characterized by disordered atrial activity and subsequent complications such as stroke and myocardial infarction, resulting in a high risk of death. Disability and mortality seriously endanger human health and life. The algorithm to study whether there is atrial fibrillation in the ECG signal can detect and treat it early, so as to seize the best time for treatment and reduce the morbidity and mortality of atrial fibrillation, so it has important clinical and social significance. [0003] Since the two important clinical manifestations of atrial fibrillation are absolute irregularity of ...
