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 , for determining the change characteristics of the PR interval according to the P wave waveform information; the second determination module is connected with the extraction module, and is used for determining the change characteristics of the RR interval according to the QRS wave waveform information; the calculation module is connected with the second determination module, using The entropy estimation method is used to calculate the sample entropy of the change characteristics of the RR interval; the third determination module is connected with the first determination module and the calculation module, and is used to determine the ECG Whether the signal is atrial fibrillation. 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 ...
