Arrhythmias are treated with antiarrhythmic drugs, radiofrequency ablation, and surgical procedures. Among them, antiarrhythmic drug therapy is a treatment for the symptoms, which requires long time maintenance medication. It may have side effects and drug-induced arrhythmic effects. Some drugs can reduce the occurrence of arrhythmia but increase the mortality rate of patients. Surgical procedures require open-heart surgery, which is very traumatic and rarely used nowadays. Radiofrequency ablation is a method that is less invasive, has immediate effect, and can achieve the purpose of radical treatment, which is the gospel of modern medical technology to the majority of arrhythmia patients. During the procedure, the patient is awake, except for the slight discomfort and tension similar to intravenous injection during the puncture, there is no additional pain to the patient. The patient can be out of bed in 6-8 hours after the procedure and can be discharged the next day. From an economic point of view, early RF ablation is also cost-saving.
