What is atrial fibrillation

summary

During the physical examination, many people will see the word atrial fibrillation in the physical examination report. Patients with mild symptoms of atrial fibrillation usually do not have any discomfort symptoms. Patients with severe symptoms will have tachycardia, palpitation, heart failure and other symptoms. Now I will share with you what is atrial fibrillation.

What is atrial fibrillation

The term atrial fibrillation defines the location and characteristics of a specific type of arrhythmia. Abnormal rhythm originates from atrium and has the characteristics of fibrillation. Fibrillation is characterized by rapid and disordered fibrillation. Atrial rhythm increases to 300-600 beats per minute, up to six times of normal heart rate.

If not treated, the rapid and disordered heartbeat of atrial fibrillation will weaken the contractility of myocardium. As time goes on, the heart muscle will become longer and thicker, making it more difficult for the heart to contract and pump blood normally.

Atrial fibrillation is associated with a variety of diseases, including hypertension, arteriosclerosis, heart failure, coronary artery disease and other types of heart diseases, such as valvular disease, pericarditis (inflammation of the cardiac capsule), congenital heart defects and chronic lung diseases.

matters needing attention

People with atrial fibrillation must pay special attention in life. They can't smoke or drink alcohol. Both smoke and alcohol are toxic to the body. Nicotine in smoke and alcohol are substances that increase the burden on the heart. Therefore, smoking cessation and alcohol abstinence are the first things to pay attention to in the diet of atrial fibrillation.
