Abstract

The invention discloses a portable atrial fibrillation detecting device and a detecting method. The portable atrial fibrillation detecting device can be carried with a patient in use, so that the patient can detect electrocardiosignals at any time; a controller inputs the detected electrocardiosignals into a stochastic resonance model to enable the stochastic resonance model to generate resonance; the controller calculates output signal-to-noise ratios (SNRs) of the stochastic resonance model, extracts an SNR average value and a SNR maximum value of atrial fibrillation characteristics from the electrocardiosignals, further judges whether atrial fibrillation happens or not, and sends safety or alarm information timely. The portable atrial fibrillation detecting device has the advantages of capabilities of monitoring the electrocardiosignals in real time and timely sending the alarm information when the atrial fibrillation happens, high detection efficiency and good accuracy.

Description

technical field [0001] The invention relates to the technical field of electrocardiogram (ECG) signal analysis, in particular to a portable atrial fibrillation detection device and 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 ...
