What is atrial fibrillation?
Atrial fibrillation , also known as Afib , is a term used to describe heart disorder. Atrial fibrillation is a form of heart arrhythmia, which means that the normal rhythm of the heart is interrupted. The condition can be permanent, can come and leave without treatment, or can only be stopped by treatment.
Atrial fibrillation can cause heart palpitations, chest pain, dizziness, shortness of breath, weakness and fatigue, although many people do not experience any symptoms at all. It is estimated that approximately two million people in the United States are experiencing atrial fibrillation. Although the condition itself is not generally fatal, this can lead to an increased risk of stroke, heart failure and heart attack.
heart disease and high blood pressure are two main known causes of atrial fibrillation. Both of these conditions can cause heart damage, so it is more susceptible to cardiac arrhythmia. Other common causes are the abnormalities of the heart of the Nebovady, the disease, sleep apnea and metabolic or chemical imbalance in the body.
the heart consists of four toOmor. The two best chambers are known as atriums and the lower two chambers are known as the chamber. All chambers must be downloaded or expanded at exactly the right time to ensure that the blood is received from the body, oxygenated and then effectively pumped back into the body.
After the body has exhausted oxygen in the blood, it enters the heart through the right hall. From the right atrium, the blood is pumped into the right ventricle, where it is pumped into the lungs, supplementing blood with oxygen. After replenishment of oxygen, the blood is transported from the lungs to the left atrium, where it is pumped into the left ventricle. From the left ventricle flows blood rich in oxygen into the aorta, which is the largest artery in the body. From aorta, blood repeats blood circulation and is distributed throughout the body.
In a healthy heart, regular electrical impulses of the heart say, where to spread and download. During atrial fibrillation, electrical pulses are irregular and very fast. This causes the left and right network to shake the minone hundred efficient beating. As a result of irregular heart rhythm, the atrium does not have to fully pump all the blood in it, which may cause blood to undress and collect.
When blood is allowed to collect, clots are more likely to be formed. If a piece of blood clots is detached and flows out of the heart, it can be stored in the artery of the brain and cause the blood flow to the brain, resulting in a stroke. It is estimated that approximately 15% of patients who experienced a stroke also experienced atrial fibrillation.
The treatment of atrial fibrillation in general is that it prevents blood clots from forming and restoring regular rhythm to Heart. Blood thinning and garbage medicines are often prescribed to reduce the risk of stroke. Drugs can also help regulate the rhythm and speed of the heart. In addition to medicines, treatment can also consist of surgical and non -surgical procedures to restore normal rhythm into the heart.
