Abstract

The invention provides an atrial fibrillation detection device and a storage medium, which comprises an extraction module for extracting P-wave and QRS-wave waveform information in an ECG signal; a first defined module is connected with the extraction module to determine the PR interval change characteristics according to the P-wave waveform information. A second defined module is connected with the extraction module to determine the characteristics of RR interval change according to the waveform information of QRS wave. A calculation module is connected with the second defined module to calculate the sample entropy of RR interval change characteristics by entropy estimation method. A third defined module is connected with the first defined module and the calculation module to determine whether the ECG signal is atrial fibrillation according to the characteristics of PR interval change, sample entropy and preset classification model. The atrial fibrillation detection device and storagemedium 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 ...
