Problems solved by technology

Due to the differences in individual ECG waveforms and the impact of noise on the ECG signals collected by wearable devices, and because the R peak is the most prominent feature point in the ECG signal, the current atrial fibrillation detection algorithm for wearable ECG is AF detection algorithm based on RR interval, but AF detection algorithm based on RR interval is easy to misjudge non-AF patients with irregular RR interval as AF

Abstract

The invention discloses a paroxysmal atrial fibrillation scanning method for long-range electrocardio monitoring, which comprises the following steps of: 1, acquiring an electrocardio waveform signal, and carrying out unified dimension processing on the signal; 2, positioning suspected atrial fibrillation, performing feature point detection on the signal, extracting an RR interval, calculating a delta RR interval, screening the suspected atrial fibrillation, and excluding part of premature beat; 3, roughly detecting atrial fibrillation, and calculating RR interval characteristics to further determine atrial fibrillation fragments; 4, fine detection of atrial fibrillation: intercepting 1 / 2 of atrial fibrillation heartbeat according to the R peak position, quantifying P-wave information, and carefully screening the atrial fibrillation according to the quantified P-wave information; and 5, finally outputting the typical waveform of the atrial fibrillation and the occurrence frequency and the occurrence frequency of the atrial fibrillation. The occurrence frequency and frequency of atrial fibrillation have important values for selection of atrial fibrillation operations, drug intervention and diagnosis and treatment of various clinical complications, and clinicians can be guided to carry out personalized treatment schemes.

Description

technical field [0001] The invention belongs to the technical field of electrocardiographic signal processing, and in particular relates to a paroxysmal atrial fibrillation scanning method, system, storage medium and electronic equipment for long-distance electrocardiographic monitoring. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] Atrial fibrillation (AF) refers to the rapid and irregular fibrillation emanating from the atrium. Paroxysmal atrial fibrillation (Paroxysmal Atrial Fibrillation, PAF) is the initial stage of atrial fibrillation, is one of the most common types of arrhythmia. About 18% of PAF will develop into permanent AF within 4 years, and PAF will worsen over time and negatively affect the patient's quality of life. Current AF guidelines recommend screening for AF in individuals over the age of 65 or with other charact...
