First, how many patients with atrial fibrillation can be solved by radiofrequency ablation technology? Atrial fibrillation is a very common disease, affecting a very large number of people, according to the recognized figures of domestic experts, there are 8 million patients with atrial fibrillation in China, most of whom are persistent chronic atrial fibrillation. 1, Catheter ablation technology emerged relatively late, and many patients with atrial fibrillation turn to chronic. 2, catheter ablation addresses a limited number of patients, because we have limited atrial fibrillation centers and limited operators, and most patients are still unresolved. 3, attention to atrial fibrillation has only begun to be paid in recent years, and the previous understanding and concept of atrial fibrillation drug therapy, clinical thinking, and complication prevention have not taken shape. So many years ago very light typical atrial fibrillation patients to now become chronic persistent atrial fibrillation, before the normal heart function of patients become now poor heart function. Now, the most difficult task for our doctors is how to let these patients with chronic atrial fibrillation receive standardized guidance and treatment from doctors, to take medication and follow up, and to treat some complications in a standardized way. What is the problem that can be solved by catheterized radiofrequency ablation therapy now? It can solve some patients who are willing to ablate, especially those who have more serious symptoms, atrial fibrillation seriously affects the quality of life and poor cardiac function, and these patients should be treated more. Radiofrequency ablation for atrial fibrillation is currently the most definitive contraindication to thrombosis, and the patient has some other acute diseases, in addition, as long as the ablation treatment is considered to be more beneficial to the patient, the treatment can be carried out. Second, which patients with atrial fibrillation are the best candidates for radiofrequency ablation therapy? 1, typical paroxysmal atrial fibrillation, young, no systemic heart disease, frequent attacks, no heart enlargement, such patients are the most typical, the success rate of one radiofrequency ablation can reach 80% to 90%. 2. Patients with atrial fibrillation lasting less than one year, with paroxysmal atrial fibrillation, not particularly large heart, no underlying disease, or patients with high risk factors for stroke after sustained atrial fibrillation. 3, choose, atrial fibrillation lasts more than a year, the medical history is unknown, may have become large atria, and there are some atrial fibrillation-related diseases, treatment should be difficult. These three types of patients a radiofrequency ablation treatment success rate, from 80%, 70% to 60%, if said to do two radiofrequency ablation, each can be increased by another 10 percentage points, of course, this is on the basis of the conditions and experience. Third, how should the general public recognize the disease of atrial fibrillation? First of all, the public should be aware of the danger of atrial fibrillation, and clearly seek medical treatment if they are sick and uncomfortable, which is the first step. The second point is that after atrial fibrillation is identified, treatment should be carried out according to the recommendations of the standard physicians. For atrial fibrillation treatment, it should be very well understood by all internists, which is not the case now. To make patients aware of the dangers of atrial fibrillation, to reduce the rate of disability and death after atrial fibrillation, and to be able to standardize the treatment, some work has to be done at both levels. On the one hand, it is necessary to improve the business ability of doctors themselves, and at the same time to strengthen patient education. Of course, a more important issue is that large hospitals in central cities should have a dedicated atrial fibrillation clinic. The most important job of the atrial fibrillation center is not to do radiofrequency ablation, but to give patients good guidance on psychological, physiological and disease aspects, and to use appropriate means to reduce the harm of atrial fibrillation to a minimum. Because 8 million patients with atrial fibrillation is a very large number, it is an important task for every doctor to pay attention to this group of people.
