Embodiment Construction

[0065] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0066] The present invention proposes a detection method for atrial fibrillation, the overall flowchart, please refer to figure 1 ,

[0067] Step 101: Obtain ECG signal data, including the RR interval, that is, the distance between two adjacent QRS waves, the heartbeat type of each corresponding heartbeat, that is, whether the heartbeat is premature ventricular beat, and the corresponding Whether there is P for a heartbeat.

[0068] Obtain input data, including the RR interval, which is the distance between two adjacent QRS waves, denoted as RR[i], and the corresponding heartbeat type of each heartbeat, that is, whether the heartbeat is premature ventricular beat, denoted as pvc[i], And whether there is a P wave in each corresponding heartbeat ...

Abstract

The invention relates to an atrial fibrillation detection method and system. A condition that whether signals have P wave or not is added while the characteristic reflecting RR interval irregularity of the ECG signals is extracted, so that the problem of false detection of sinus arrhythmia signals is solved; a BP neural network method is adopted to replace simple logic conditions to judge atrial fibrillation signals, so that atrial fibrillation detecting accuracy when input RR interval number is small is improved.

Description

technical field [0001] The invention relates to a method for detecting atrial fibrillation, and at the same time, the invention also relates to a detection system for atrial fibrillation. Background technique [0002] Atrial fibrillation is one of the most common arrhythmias, with an incidence rate of 0.3% to 0.4% in adults. With the increase of age, the incidence rate doubles, and the incidence rate of those over 75 years old is close to 10%. Electrical activation of the normal heart begins at the sinoatrial node. Since the sinoatrial node is located at the junction of the right atrium and the superior vena cava, the excitation of the sinoatrial node is first transmitted to the right atrium, and then transmitted to the left atrium through the interatrial bundle, forming a P wave on the electrocardiogram. The excitation is conducted to the atrioventricular node along the antero-middle-posterior nodal bundle. Due to the slow conduction velocity of the atrioventricular node,...
