Abstract

The invention relates to atrioventricular block detection method, apparatus and electronic equipment base on electrocardiograph signals. The atrioventricular block detection method comprises the following steps: extracting signal waveform from an electrocardiograph signal; acquiring an atrioventricular block characteristic of the signal waveform, wherein the atrioventricular block characteristic is any one selected from correlation value of power spectral density, PR interval duration and a PR interval variation parameter; inputting the atrioventricular block characteristic into a detector; and then, acquiring detection result outputted by the detector so as to obtain the signal type of the electrocardiograph signal, wherein the detection result is a result detected by the detector according to the atrioventricular block characteristic, and the signal type include atrioventricular block and non-atrioventricular block. Being adopted, the atrioventricular block detection method is capable of more accurately identifying atrioventricular block so as to avoid the condition that non-atrioventricular block is wrongly identified as atrioventricular block due to individual differences; andthus, accuracy of atrioventricular block detection is improved.

Description

technical field [0001] The present application relates to the field of medical devices and medical products, in particular to a method, device, electronic device and storage medium for detecting atrioventricular block based on electrocardiographic signals. Background technique [0002] Atrioventricular block (AVB) is a type of heart electrical conduction system block disease, mainly including first-order block, second-order block and third-pole block, and the block level is from atrium to ventricle. Conduction severity is determined, and this type of atrial-ventricular depolarization mismatch gives ECG changes, so AV block can be identified by ECG feature extraction. [0003] However, since the recognition of atrioventricular block reflected on the ECG is relatively complicated, it is difficult to meet the clinical diagnostic standards in terms of reliability and accuracy only by manually extracting a few features, combined with traditional machine learning methods. [0004...
