Title:
ATRIAL FIBRILLATION DETECTION DEVICE AND METHOD, AND SYSTEM AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2022/073220
Kind Code:
A1
Abstract:
An atrial fibrillation detection device and method, and a system and a storage medium. The device comprises: an electrocardiogram signal processing module, used for recognizing positions of points P, Q, R, S, and T of each heartbeat in an electrocardiogram signal obtained within a preset duration, and determining an RR interval, the amplitude of the point P, the amplitude of the point R, and TQ segment waveforms; and a detection module, used for obtaining a fusion score and performing condition determination on the fusion score and a fifth score to determine the suspicion degree of atrial fibrillation, the fifth score being a quotient of the total number of f waves of all TQ segment waveforms and the total number of TQ segment waveforms comprised in the electrocardiogram signal, the f wave of each TQ segment waveform being in a waveform greater than respective f wave amplitude threshold and having a width greater than a width threshold. The device first obtains the fusion score by means of four models, and performs condition determination according to the fusion score and the fifth score to obtain the suspicion degree of atrial fibrillation, such that the severity of suffering atrial fibrillation can be effectively and accurately obtained, determination of the condition of a patient is facilitated, and the patient with mild atrial fibrillation can be treated in time.
