Atrial fibrillation automatic detection system based on smartphone

Abstract

The invention provides an atrial fibrillation automatic detection system based on a smartphone. The atrial fibrillation automatic detection system based on the smartphone does not need additional hardware and only needs the smartphone provided with an atrial fibrillation automatic detection application program. When detection is conducted, people gently put the fingertips on a camera and an LED flash lamp of the smartphone, pulse waves is extracted from images taken by the smartphone, the electrocardio R-R interphase is obtained, and therefore atrial fibrillation can be automatically detected by means of the R-R interphase and the generality density function algorithm. The atrial fibrillation automatic detection system based on the smartphone is cheap, simple, easy to use, capable of being used anytime and anywhere, easy to popularize, and capable of detecting more patients who suffer atrial fibrillation, enabling the patients to receive timely diagnosis and treatment, reducing the possibility of stroke and the medical cost and having significant social and economic value.

Description

technical field [0001] The present invention generally relates to a method and a device, a smart phone with an automatic detection function for atrial fibrillation. Background technique [0002] Atrial fibrillation is a common clinical arrhythmia. The incidence rate increases with age. It is 0.5% before the age of 60, more than 5% over the age of 65, and more than 10% over the age of 80. For every 10-year increase in age, the incidence of atrial fibrillation increased by 1.4 times. The Minnesota study in the United States showed that the incidence of atrial fibrillation increased significantly between 1980 and 2000, and it is estimated that by 2050, the number of patients with atrial fibrillation in the United States will reach 12 million. 35% of the new patients with atrial fibrillation were caused by the increase in the incidence of atrial fibrillation, 45% were caused by the increase in the average life expectancy, and only 22% of the patients with atrial fibrillation we...

AI Technical Summary

Problems solved by technology

Due to asymptomatic or mild symptoms, most patients do not realize that they have atrial fibrillation and do not seek medical advice, and cannot receive timely antithrombotic treatment

In other patients with paroxysmal atrial fibrillation, because atrial fibrillation only occurs occasionally, the electrocardiogram or even the 24-hour dynamic electrocardiogram in the hospital cannot capture the onset of atrial fibrillation, resulting in missed diagnosis
