The success rate of radiofrequency ablation for preexcitation syndrome is more than 90%, which is related to the experience of the operator and has the risk of recurrence, which requires more clinical observation.
Pre-excitation syndrome is due to congenital heart development abnormality, during the attack, there will be palpitations, chest tightness, fainting and other symptoms, and in severe cases, even ventricular fibrillation will be life-threatening.
Currently, the effective treatment for pre-excitation syndrome is radiofrequency ablation, in which an electrode catheter is inserted into the heart through a vein, and electrophysiological marking technology is used to find the abnormal electrical conduction channels in the heart, and the electrode at the tip of the catheter is used to produce a resistive electrothermal effect, which leads to necrosis of cardiac myocytes, and thus achieves the goal of healing.
The prognosis of patients after radiofrequency ablation for preexcitation syndrome is good, with a high success rate, few complications and a low recurrence rate. However, there is still a possibility of recurrence, patients should pay attention to regular daily routine, closely observe the changes in the condition, and seek timely medical treatment when necessary.
