Cardiac preexcitation surgery usually takes the form of catheterized radiofrequency ablation, which is minimally invasive and not a major surgery. Patients with cardiac pre-excitation do not need to take any treatment if they are asymptomatic. If the symptoms are mild, conservative treatment should be the main treatment, and if necessary, choose surgical treatment, but the surgery mostly choose catheter radiofrequency ablation, which is minimally invasive surgery, not major surgery. Catheter radiofrequency ablation is one of the methods of treating arrhythmia. The surgery is monitored by X-ray angiography machine, puncturing the blood vessels and inserting the electrode catheter into the heart to clarify the location of the abnormal structure of the tachycardia, and then releasing the high-frequency electric current locally, which will make the water in the tissues of the place evaporate and necrotic through the thermal efficacy to achieve the therapeutic purpose. For patients with cardiac preexcitation, if surgical treatment is needed, they should go to a local regular hospital and consult their doctors in detail. Keep a good mood during the period and avoid too much tension.
