Atrial fibrillation is a type of heart rate disorder. The full name of atrial fibrillation is atrial fibrillation or atrial fibrillation, which, as the name implies, is a disorderly beating of the atria. The heart has four chambers, including two atria and two ventricles. When the atria contract, they drive the ventricles to contract, a process we often refer to as a heartbeat. The contraction of the heart can drain the blood to the surrounding arteries and then flow to the whole body, thus causing blood circulation. Once the atrium is disordered, there will be chaotic beating, and very fast chaotic beating, which will cause the disorder of the ventricle, and the disordered beating of the ventricle will cause our heartbeat to be chaotic, that is, our heart rate is not normal. This heart rate disorder is a rapid heart rate disorder, and atrial fibrillation is one of the rapid heart rate disorders, and it is a very common type. Atrial fibrillation can cause a lot of harm, and rapid arrhythmias can cause functional heart problems, such as heart failure, which is often referred to as heart failure, with symptoms such as breathlessness or lying down. Atrial fibrillation can lead to stagnation of blood in the atria, which can lead to the formation of blood clots in the atria, causing embolism, and if this embolism is blocked in the brain, it can easily cause stroke, hemiplegia, and unfavorable speech.
