Radiofrequency ablation for atrial fibrillation is a minimally invasive treatment method, which is widely used in clinic. Its principle is to do electrophysiological examination first to find out the part that causes atrial fibrillation, and then convert electric energy into heat energy through radiofrequency ablation to completely destroy the focus that causes atrial fibrillation, so as to achieve the goal of completely curing atrial fibrillation.

Radiofrequency ablation for atrial fibrillation has the advantages of less trauma, quick recovery and high success rate. At present, it has been used in clinic for many years and is the first choice for the treatment of atrial fibrillation. Especially in the case of permanent atrial fibrillation and drug treatment can not be completely controlled, radiofrequency ablation can be considered to deal with it.

The surgical method of radiofrequency ablation of atrial fibrillation is to puncture venous blood vessels, generally choose femoral vein or subclavian vein, insert electrode catheter into the heart along venous blood vessels, and monitor the catheter position under X-ray angiography machine. The next step is to check the abnormal discharge potential that causes arrhythmia. High-frequency current is generated at the end of the catheter through thermal efficiency or freezing, so that the local abnormal discharge potential causes coagulation and necrosis of myocardial cells, and the abnormal discharge potential can be interrupted.

Generally, the damage range is very small, with a diameter of about 3-4mm, which will not affect normal myocardial tissue, and patients generally have no obvious symptoms during operation. It is generally recommended to use antiarrhythmic drugs and anticoagulants for a period of time after operation.
