Atrial fibrillation detection device and storage medium

Abstract

The present invention provides an atrial fibrillation detection device and a storage medium. The atrial fibrillation detection device includes: an extraction module for extracting P wave waveform information and QRS wave waveform information in ECG signals; a first determination module connected to the extraction module , used to determine the P wave change characteristics according to the P wave waveform information; the second determination module is connected to the extraction module and used to determine the PR interval change characteristics according to the QRS wave waveform information; the third determination module is connected to the extraction module for Determine the RR interval change characteristics according to the QRS wave waveform information; the calculation module is connected with the third determination module, and is used to calculate the information entropy of the RR interval change characteristics by using the entropy estimation method; the fourth determination module is connected with the first determination module and the second determination module. 2. The determination module is connected with the calculation module, and is used to determine whether the electrocardiographic signal is atrial fibrillation according to the change characteristics of the P wave, the change characteristics of the PR interval, information entropy and a preset classification model. The invention can improve the robustness of atrial fibrillation detection.

Description

technical field [0001] Embodiments of the present invention relate to signal processing technologies, and in particular to an atrial fibrillation detection device and a storage medium. Background technique [0002] Atrial fibrillation (AF) is a relatively common arrhythmia disease in clinical practice, which is characterized by disordered atrial activity and subsequent complications such as stroke and myocardial infarction, leading to high The disability rate and mortality rate seriously endanger human health and life. In order to detect and treat early and reduce the morbidity and mortality of atrial fibrillation, research on the detection of atrial fibrillation has important clinical and social significance. [0003] However, most of the existing research on AF detection focuses on a certain clinical manifestation of AF, which has poor robustness and is difficult to meet clinical needs. Contents of the invention [0004] Embodiments of the present invention provide an ...
