What disease is atrial fibrillation

summary

Atrial fibrillation is the abbreviation of atrial fibrillation, which is a kind of arrhythmia. There are many pathogenic factors, and stroke is the most serious harm. Let's take a look at what atrial fibrillation is.

What disease is atrial fibrillation

First of all: atrial fibrillation (AF) is the most common persistent arrhythmia. With the increase of age, the incidence of atrial fibrillation is increasing, up to 10% of the population over 75 years old. The frequency of atrial activation in atrial fibrillation is 300-600 beats / min, and the heart rate is often fast and irregular, sometimes up to 100-160 beats / min, which is not only much faster than that in normal people, but also absolutely irregular, and the atrium loses its effective systolic function.

Secondly: the common causes of atrial fibrillation include hypertension, coronary heart disease, cardiac surgery, valvular disease, heart failure, cardiomyopathy, congenital heart disease, pulmonary embolism, hyperthyroidism, etc., which are related to drinking, mental tension, water electrolyte disorder, severe infection, etc.; in addition, other types of arrhythmias can be combined. It is very important to find out the cause actively after the illness.

Finally: stroke is one of the greatest hazards of atrial fibrillation. The incidence of stroke in patients with non valvular atrial fibrillation is 5.6 times higher than that in normal people, and the incidence of stroke in patients with valvular atrial fibrillation is 17.6 times higher than that in normal people. Moreover, the consequences of stroke caused by atrial fibrillation are more serious.

matters needing attention

Some patients may need to avoid caffeine containing substances such as tea, coffee, cola and some over-the-counter drugs. Usually in the cold or cough, should be careful use of drugs.
