The risk of permanent atrial fibrillation?

summary

Atrial fibrillation (AF) is one of the most common arrhythmias, which is caused by many small reentry loops. It is found in almost all organic heart disease, and can also occur in non organic heart disease. It causes serious complications, such as heart failure and arterial embolism, which seriously threaten people's health. Next, I'll tell you something.

The risk of permanent atrial fibrillation?

When atrial fibrillation occurs, the atrium loses its contractile function, and the blood is easy to stagnate in the atrium and form thrombus. After the thrombus falls off, it can go to all parts of the body with the blood, leading to cerebral embolism (stroke), limb arterial embolism (even amputation in severe cases), etc.

The risk factors of stroke in patients with atrial fibrillation include previous history of embolism, hypertension, diabetes, coronary heart disease, heart failure, left atrial enlargement, and age over 65. The loss of atrial systolic function and long-term increase of heart rate during atrial fibrillation can lead to heart failure and increase mortality (2 times of that in normal people).

Differentiation of atrial fibrillation from other irregular tachyarrhythmias: typical atrial fibrillation waves in ECG can be distinguished from supraventricular tachycardia or atrial flutter with irregular block. The ECG manifestations of AF with complete bundle branch block or preexcitation syndrome may be similar to ventricular tachycardia. Careful identification of the obvious irregularity of AF and ventricular rhythm is conducive to the diagnosis of AF.

matters needing attention

Some patients may need to avoid caffeine containing substances such as tea, coffee, cola and some over-the-counter drugs, and be cautious in using certain cough or cold drugs, which may contain stimulants, which may promote irregular heart rhythm, Before taking it, you should ask your doctor or read the instructions to see if it is suitable for you.
