What is Cardiac radiofrequency Ablation Needle Surgery?

After many patients develop arrhythmias, they often hear from their doctors that radiofrequency ablation is recommended. So what is radiofrequency ablation of arrhythmias. Arrhythmia is a kind of heart disease caused by one or more abnormal occurrence of the location, frequency, rhythm, conduction time or conduction pathway "short circuit" of the origin of cardiac excitement. In our country, the patients with tachycardia alone have reached more than 5 million. Normal cardiac excitation in the human body originates from the sinoatrial node in the heart, and then passes through the internodal bundle, the AV node, his bundle, the left and right bundle branches and Purkinje fibers to the ventricle. This rhythm is called sinus rhythm. Different types of arrhythmias can occur when the origin and conduction pathways of the heart are changed. Common arrhythmias include sinus tachycardia, sinus bradycardia, sinus arrhythmia, premature beat, paroxysmal tachycardia, atrial fibrillation, atrioventricular block and so on. Clinically, chest pain, palpitation, abnormal pulse symptoms as the main manifestations, severe cases may appear dizziness, dizziness, shortness of breath, sweating out cold limbs and other symptoms. Clinical electrophysiological studies have shown that arrhythmia is closely related to the internal variation of myocardial tissue, which has become the pathologic and anatomical basis of radiofrequency ablation for the treatment of arrhythmia. The principle of the treatment of arrhythmia is to irreversibly destroy or remove these abnormal myocardial tissues through drugs, surgery and other methods. Arrhythmia is one of the common heart diseases with high morbidity and mortality. Therefore, the treatment of arrhythmia has been paid more attention by the medical community all over the world. In the past, there have been some drugs to treat arrhythmias, but most of them only provide temporary relief. Moreover, due to the diversity of arrhythmias, it is a very heavy and difficult work to find the drug suitable for a patient in clinical practice, and long-term medication will lead to drug dependence. The most direct way to cure arrhythmia is heart surgery, but the high risk of surgery is not for everyone. With the deepening of basic research and the continuous emergence of new technologies and new materials, radiofrequency ablation (RFA), an interventional non-surgical method for treating arrhythmias, has entered the clinic. This method is to deliver some form of energy to the site to be ablated in the heart through the cardiac catheter, and cause irreversible damage to the lesion site. Clinical practice has proved that radiofrequency ablation provides a fast, safe and effective treatment method for many patients with arrhythmia, which makes patients get rid of the dependence and fear of cardiac surgery, and also greatly reduces the treatment cost and cost. Human heart tissue, like other tissues in the body, is a heat-tolerant substance. When heat flows into or is generated in any heart tissue, part of the heat is absorbed by the tissue and this is the material basis for ablation. Radiofrequency ablation is a method of irreversibly destroying or removing abnormal myocardial tissue. Radiofrequency ablation has been gradually applied in clinical practice since 1990s. Doctors do not need to make an operation, but simply send radiofrequency current through a venous or arterial cardiac catheter through the venous pinhole and send it to the diseased site of the heart under X-ray monitoring and guidance. The radiofrequency current flows into the heart tissue at the ablation site and passes a certain temperature. The treatment is achieved by artificially altering or removing the abnormal or proliferative tissue in the heart that produces the arrhythmia. How safe is radiofrequency ablation as a new cardiac interventional therapy? Radiofrequency ablation (RFA) is a safe and reliable treatment for arrhythmias with mild myocardial injury but without obvious clinical manifestations and adverse consequences. The resulting further damage is also limited and minimal. Therefore, radiofrequency ablation is a safe and reliable method for cardiac interventional therapy in clinic. Experts pointed out that, like any advanced medical technology, radiofrequency ablation technology is not perfect at present. The main problems are: it is difficult to establish the elimination end point, which needs long-term follow-up; Arrhythmias may recur due to the recurrence of ablation lesions or the generation of new lesions, so the indications need to be strictly controlled. How much does the conventional radiofrequency ablation cost? For a common two-dimensional radiofrequency ablation, the out-of-pocket cost for an operation is about 20,000 yuan. Attend THE PATIENT OF MEDICAL INSURANCE, ACCORDING to each DISTRICT MEDICAL insurance CIRCUMSTANCE AND DECIDE. In general, radiofrequency ablation is a relatively perfect method for the treatment of arrhythmia. Since the development of the technology, it has solved the suffering of countless patients with arrhythmia for decades, and got rid of the hat of heart disease.
