Radiofrequency ablation is not a major surgery, it is a minimally invasive procedure. Radiofrequency ablation is a procedure in which a catheter is placed retrogradely into the atrium along the aorta, and then radiofrequency current is introduced to cause coagulative necrosis of the local endocardium as well as the myocardium under the endocardium, so as to block the conduction of the abnormal heart rhythms, and to restore the heart’s normal rhythms. Minimally invasive surgery is less invasive and the patient recovers faster after surgery. Usually, the punctured limb needs to be braked for 4 to 8 hours after the operation, and observe whether there is bleeding and hematoma, and closely monitor the patient’s electrocardiographic status, vital signs and arterial pulsation. Patients undergoing radiofrequency ablation should go to regular hospitals for diagnosis and treatment, and be on high alert for complications such as bleeding, infection, arrhythmia and cardiac tamponade after the procedure.
