Abstract

The invention discloses an atrial fibrillation detection device and detection method. The atrial fibrillation detection device can be placed in places such as a house of a patient or an office of the patient. Only one atrial fibrillation detection device can accurately detect whether atrial fibrillation happens or not, and other detection devices are not required to be matched with the atrial fibrillation detection device. A computer inputs detected digital electrocardio signals into a stochastic resonance model, resonance is generated by the stochastic resonance model, and the computer computes an output SNR of the stochastic resonance model, extracts the SNR mean value and the SNR maximum value of atrial fibrillation characteristics from the digital electrocardio signals, further makes the judgment on whether the atrial fibrillation happens or not, and timely gives out safety information or alarm information. According to the atrial fibrillation detection device and detection method, the electrocardio signals can be detected at any time, the alarm information can be timely given out, and the atrial fibrillation detection device has the advantages of being high in detection efficiency and good in accuracy.

Description

technical field [0001] The invention relates to the technical field of electrocardiogram (ECG) signal analysis, in particular to an atrial fibrillation detection device and a detection method capable of accurately extracting characteristics of atrial fibrillation from electrocardiographic signals. Background technique [0002] Usually, an excitation from the sinoatrial node in the human body is transmitted to the atrium and ventricle in turn according to a certain route and process, causing the excitement of the whole heart; There are certain rules in the direction, route, sequence and time of transmission. This bioelectrical change is reflected to the surface of the body through the conductive tissue and body fluid around the heart, causing regular electrical changes in all parts of the body in each cardiac cycle. The electrical change curve of the heart recorded by placing the measuring electrodes on a certain part of the surface of the human body is the clinically record...
