Description
技术领域technical field
本发明涉及生物电信号检测领域，具体涉及一种基于健康监测手环的自助房颤检测方法。The invention relates to the field of bioelectrical signal detection, in particular to a self-service atrial fibrillation detection method based on a health monitoring bracelet.
背景技术Background technique
心房颤动简称房颤，是最常见的心律失常之一。它几乎见于所有的器质性心脏病，在非器质性心脏病也可发生。一旦发生心房颤动，严重威胁人体健康。常见危害有：①血栓形成与栓塞：房颤时心房丧失正常规律的舒缩功能，血液容易在心房内淤滞而形成血栓，血栓脱落可随着血液至全身各处，导致脑栓塞(中风、偏瘫)、肢体动脉栓塞(严重者甚至需要截肢)等。在不伴有其它疾病、年龄小于60岁的房颤病人，脑卒中的年发生率为1％左右，而在60-75岁以上的病人，脑卒中的年发生率为2％。如果伴有其它栓塞高危因素，则脑卒中的年发生率可达4％。房颤患者脑卒中的高危因素包括以前有栓塞病史、高血压病、糖尿病、冠心病、心衰、左心房扩大、年龄超过65岁等。②心率快和节律不整齐可使病人感到心悸。③心房收缩功能丧失和长期心率增快可导致心力衰竭。④增加死亡率(是正常人的2倍)。随着年龄增长，房颤的发生率不断增加，到了70岁将近10％的人会发生房颤，到了80岁提高到20％。房颤患者死亡危险较无房颤者高1.5～1.9倍。严重房颤发生时需要及时诊治，否则将可能危及生命。Atrial fibrillation, abbreviated as atrial fibrillation, is one of the most common heart rhythm disorders. It is found in almost all structural heart diseases, and can also occur in non-structural heart diseases. Once atrial fibrillation occurs, it will seriously threaten human health. Common hazards include: ①Thrombosis and embolism: During atrial fibrillation, the atrium loses its regular diastolic and contractile functions, and blood easily stagnates in the atrium to form thrombus. ), limb arterial embolism (serious cases even require amputation), etc. In patients with atrial fibrillation without other diseases and younger than 60 years old, the annual incidence of stroke is about 1%, while in patients over 60-75 years old, the annual incidence of stroke is 2%. If accompanied by other high-risk factors for embolism, the annual incidence of stroke can reach 4%. Risk factors for stroke in patients with atrial fibrillation include previous history of embolism, hypertension, diabetes, coronary heart disease, heart failure, enlarged left atrium, and age over 65 years old. ② fast heart rate and irregular rhythm can make patients feel palpitations. ③ Loss of atrial systolic function and long-term increased heart rate can lead to heart failure. ④Increased mortality (twice that of normal people). The incidence of atrial fibrillation continues to increase with age, nearly 10% of people will develop atrial fibrillation by the age of 70, and it will increase to 20% by the age of 80. The risk of death in patients with atrial fibrillation was 1.5 to 1.9 times higher than that in patients without atrial fibrillation. Severe atrial fibrillation requires timely diagnosis and treatment, otherwise it may be life-threatening.
目前，由于找不到跟踪房颤的状态变化和治疗效果的有效测试方法，房颤的治理基本上都是基于临床试错法，导致治疗效率的下降。目前的心电(electrocardiogram，ECG)信号都是通过体表采集得到，而这采集到的信号是心室电信号、心房电信号以及其他电信号的合成信号。现在虽然有采用心房信号和心室信号分离的方法来检测房颤，但由于噪声信号可能淹没微弱的房颤特征波-f波，所以会导致误检，准确性不高。而且，阅读心电图并根据波形的变化做出判断是一个非常复杂的过程，常常会由于医生资质及经验的不足而出现心电图的判读错误。At present, since there is no effective test method to track the state changes of atrial fibrillation and the effect of treatment, the treatment of atrial fibrillation is basically based on clinical trial and error, resulting in a decline in treatment efficiency. Currently, electrocardiogram (ECG) signals are collected through body surface, and the collected signals are composite signals of ventricular electrical signals, atrial electrical signals and other electrical signals. Although there is a method of separating the atrial signal and the ventricular signal to detect atrial fibrillation, since the noise signal may drown out the weak characteristic wave of atrial fibrillation - f wave, it will lead to false detection and the accuracy is not high. Moreover, it is a very complicated process to read the ECG and make judgments based on the changes in the waveform, and errors in the interpretation of the ECG often occur due to the lack of qualifications and experience of doctors.
