|
Atrial fibrillation is the most common persistent arrhythmia. The incidence of atrial fibrillation continues to increase with aging, and the peak incidence is over 65 years old, which can be as high as 10% in people over 75 years old. Atrial fibrillation is characterized by an irregular, usually rapid heart rate, which can increase the risk of stroke, heart failure and other heart related complications. In atrial fibrillation, the two upper chambers (atrium) of the heart beat irregularly, the atrium lost its effective systolic function, and the two lower chambers (ventricles) of the heart did not coordinate. Atrial fibrillation patients are usually flustered, shortness of breath, headache, dizziness, chills, and even limb weakness, lower limb edema. According to incomplete statistics from WHO, there are nearly 40 million AF patients in the world, and there is an increasing trend year by year. At present, there are more than 10 million patients with atrial fibrillation in China, and also more than 10 million patients in the United States and Europe. |
