Radiofrequency can refer to radiofrequency ablation of the heart, which involves passing an electrode catheter through an artery, or vein in the body to reach the diseased part of the heart, and then using the electrode to produce a thermal effect at the site, causing the heart muscle cells to coagulate and necrosis under the heat flow to block the symptoms of arrhythmia. The indications for the procedure of radiofrequency ablation are: atrioventricular node folding tachycardia, pre-excitation syndrome, atrial fibrillation, atrial flutter, and frequent supraventricular tachycardia, which can have a radical effect on these diseases, but children under three years of age with fragile hearts and thin blood vessels are not eligible for this procedure. In addition to heart, radiofrequency ablation can also be used to treat benign as well as malignant tumors in the human body, such as uterine fibroids, liver cancer or back and leg pain, cervical erosion, cervical polyps and other diseases.
