Problems solved by technology

It mainly analyzes and evaluates the irregularity of RR interval in atrial fibrillation. However, the current analysis method is too single and fails to effectively combine multiple statistical features for more effective atrial fibrillation analysis.
The calculation of some statistical parameters is complicated and cannot be applied to wearable devices for real-time diagnosis

Embodiment Construction

[0040] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other implementations obtained by persons of ordinary skill in the art without making creative efforts fall within the protection scope of the present invention.

[0041] The invention provides a method for judging atrial fibrillation; comprising the following steps:

[0042] Step 1: Use an electrocardiogram monitor to detect heart rate, and record not less than 129 consecutive heartbeats and the number of ventricular heartbeats Vum;

[0043] Step 2, counting the RR interval of the non-ventricular heartbeat;

[0044] Step 3, when the number of ventricular beats Vum50, input the non-ventricular RR interval nRR and the num...

Abstract

The invention provides an atrial fibrillation judgment method. The method is used for comprehensively judging atrial fibrillation by adopting two or more than two judgment conditions, wherein the judgment conditions can comprise: the number of different sizes between adjacent RR intervals, the specific value of the total number of turning points in the RR intervals, a difference value symbol sequence in the RR intervals, Shannon entropy and types of the RR intervals and the like. Whether the atrial fibrillation occurs or not is comprehensively judged by adopting the plurality of judgment conditions and erroneous judgment is avoided; meanwhile, 129 continuous heart beats are calculated in real time and the atrial fibrillation judgment is delayed for about two minutes; an occupied memory is small and a calculation speed is rapid; the judgment method can also be planted into wearable equipment and is more convenient for testing.

Description

technical field [0001] The invention belongs to the technical field of electrocardiographic signal monitoring and analysis, and relates to a method for judging atrial fibrillation. Background technique [0002] With the development of the economy, health issues have increasingly become the focus of people's attention. According to statistics, the incidence of cardiovascular disease is constantly increasing, and heart disease has become a major disease that threatens life and health. Atrial fibrillation is one of the most common cardiac arrhythmias in clinical practice. and increasingly younger. The diagnosis and treatment of atrial fibrillation is the research focus in the current medical field. Traditional lossy recording technology can obtain more detailed frontal and atrial activity characteristics, but the technology is complicated and requires high equipment requirements. The wearable has the characteristics of portability, real-time and fast, which is a new developm...
