Many patients who develop arrhythmias often hear from their doctors that radiofrequency ablation therapy is recommended. So what is radiofrequency ablation of arrhythmias. Arrhythmia is a type of heart disease caused by one or more abnormalities in the site, frequency, rhythm, conduction time or conduction pathway of heart excitation. Normal cardiac excitation in humans originates in the sinus node of the heart and then passes through the inter-nodal bundle, atrioventricular node, Hitchcock’s bundle, left and right bundle branches and Purkinje fibers to the ventricles, which is called sinus rhythm. Different types of arrhythmias occur when the origin of cardiac excitation and conduction pathways are altered. The common arrhythmias include sinus tachycardia, sinus bradycardia, sinus arrhythmia, premature beats, paroxysmal tachycardia, atrial fibrillation, and atrioventricular block. The main clinical manifestations are chest pain, palpitations, abnormal pulse, etc. In severe cases, symptoms such as dizziness, dizziness, shortness of breath, cold sweat, etc. may occur. Clinical electrophysiological studies have shown that arrhythmias are very closely related to the internal variability of myocardial tissue, which has become the pathological and anatomical basis for the treatment of arrhythmias by radiofrequency ablation. The principle of arrhythmia treatment is the irreversible destruction or removal of these abnormal myocardial tissues by drugs and surgery. Arrhythmias are one of the common heart diseases with high morbidity and mortality rates, therefore, the treatment of arrhythmias has been paid much attention by the medical community all over the world. Although there are some drugs for arrhythmias in the past, most of these drugs can only provide temporary relief; moreover, due to the diversity of arrhythmias, finding the right drug for a particular patient is a very heavy and difficult task in clinical practice, and long-term medication can lead to drug dependence. The most direct way to eradicate arrhythmias is heart surgery, but the high risk of surgery does not apply to everyone. With the advancement of basic research and the emergence of new technologies and materials, radiofrequency ablation, an interventional non-surgical treatment for arrhythmias, has begun to enter the clinic. This method involves delivering some form of energy through a cardiac catheter to the site to be ablated in the heart and causing irreversible damage to that lesion. Clinical practice has proven that radiofrequency ablation provides a quick, safe and effective treatment for many patients with arrhythmias, freeing patients from dependence on and fear of cardiac surgery, while greatly reducing the cost and expense of treatment. The human heart tissue is a heat-trapping substance like any other tissue in the body. When there is heat flow into any heart tissue element or heat is generated there, some of the heat is absorbed by that tissue element, which is the material basis for ablation. Radiofrequency ablation is a method of irreversibly destroying or removing abnormal myocardial tissue. Radiofrequency ablation has been gradually used in clinical practice since the 1990’s. The doctor does not need to open an incision, but simply passes a radiofrequency current through an intravenous needle hole, through a venous or arterial heart catheter, and delivers it to the diseased part of the heart under X-ray surveillance guidance. treatment purpose. Radiofrequency ablation is a new cardiac interventional technology, how safe is it? Radiofrequency ablation does cause minor myocardial damage in the treatment of arrhythmias, but there are no obvious clinical manifestations or adverse consequences, and it is a safe and reliable treatment method. The further damage caused by this is limited and minimal. Therefore, radiofrequency ablation is a safe and reliable method of cardiac intervention in clinical practice. Experts point out that, like any advanced medical technology, radiofrequency ablation technology is not perfect at present. The main problems are: it is difficult to set the elimination endpoint, which needs to be determined by long-term follow-up; the arrhythmia may recur due to the recurrence of ablation lesions or new lesions, so the indications need to be strictly controlled. How much does a routine radiofrequency ablation procedure cost?: The cost of an ordinary radiofrequency ablation procedure under two dimensions is about 20,000 for a procedure done at your own expense. For patients with medical insurance, it depends on the local medical insurance. Overall, radiofrequency ablation is currently a more perfect method for treating arrhythmias. Since the technology was launched, it has solved the pain that has plagued countless arrhythmia patients for decades and got rid of the hat of heart disease.
