What are the treatments for atrial fibrillation?

The atrium is a relatively delicate structural space in the heart. The function of the atrium is to gather blood for a short period of time, and then pump the blood to all parts of the body through the powerful power of the heart. Therefore, the size and capacity of the atrium have an important influence on the capacity of the heart. However, the atrium is a high-incidence area for heart disease, especially atrial fibrillation, which is an important cause of heart pain or heart weakness in patients. Once atrial fibrillation occurs, immediate rescue treatment is required, otherwise it will threaten life safety in a short period of time. Let's take a look at the explanation of how to treat atrial fibrillation.

Atrial fibrillation (AF) is one of the most common arrhythmias. It is an atrial rhythm with disordered excitation and ineffective contraction of the atria. It is an atrial rhythm disorder caused by many small reentry circuits caused by the dominant atrial reentry circuit. It is very common in the elderly. Atrial fibrillation can be seen in all patients with organic heart disease. It can also occur in patients with non-organic heart disease. It has a high incidence and long duration, and can also cause serious complications such as heart failure and arterial embolism. Leading to increased disability or mortality in patients.

1. Treatment of the cause

Treatment of the cause of atrial fibrillation is of vital importance. Active treatment of primary heart disease can easily convert atrial fibrillation to sinus rhythm and maintain it for a long time after conversion. Even if the cause cannot be cured, it is also important to relieve hemodynamic abnormalities. In patients with atrial fibrillation caused by ischemic heart disease, hypertensive heart disease, cardiomyopathy, etc., when myocardial ischemia is improved, heart failure is corrected, and blood pressure is well controlled, the chance of atrial fibrillation conversion increases and sinus rhythm can be maintained for a long time. For patients with rheumatic heart disease, mitral stenosis and atrial fibrillation, many patients can maintain sinus rhythm for a long time after cardioversion after surgery to remove the cause.

2. Medication

Including drug cardioversion, ventricular rate control and anticoagulation therapy.

3. Radiofrequency ablation

Radiofrequency ablation is mainly used in patients with paroxysmal atrial fibrillation who are ineffective with antiarrhythmic drugs or have obvious symptoms, as well as patients with persistent atrial fibrillation whose ventricular rate is difficult to control. The earliest method used was atrioventricular node ablation, which caused permanent complete atrioventricular block, and then combined with pacing therapy to improve the patient's symptoms and hemodynamic effects. In recent years, radiofrequency ablation has made certain progress, the efficacy has gradually improved, and it has become an important means of treating atrial fibrillation.
