Q: I am 25 years old healthy girl. The other day I had a very fast heart beat all of a sudden, in the ER the doctor told me it's Pre-excitation syndrome. With Pre-excitation syndrome, the fast heart beat might come back suddenly from time to time. Do I need to take a surgery to solve the problem? Is it worthwhile? If I take the surgery, can I recover as a normal person? Will I have bad heart function after surgery?
A: Pre-stress syndrome is due to the congenital presence of atrioventricular conduction pathway, so there is a characteristic change in the electrocardiogram. The bypass causes Paroxysmal Ventricular Tachycardia. There are no preventive measures, if it attacks the patient frequently, the patients can choose to have radiofrequency ablation treatment, which is to eliminate the bypass.
The radiofrequency ablation treatment is an effective and mature treatment method. The success rate of pre-excitation radiofrequency catheter ablation is very high, once the bypass is eliminated, the patient no longer has similar symptoms. Then the disease is completely cured.
Despite of the discomfort, the risk of Pre-excitation syndrome is more about the potential complications, mainly the rapid arrhythmia, such as atrioventricular reentrant tachycardia, atrial fibrillation. When it occurs, there's a risk of sudden death.
