Cardiac preexcitation syndrome is inherited, timely treatment is very important

Cardiac preexcitation syndrome is a manifestation of arrhythmia. If this heart disease causes tachycardia, timely surgical treatment is required. The most common treatment is radiofrequency ablation. But don't worry, cardiac preexcitation syndrome is not hereditary.

1. Is cardiac preexcitation syndrome hereditary?

Preexcitation syndrome is mainly caused by the presence of a bypass pathway in the heart, which causes reentrant tachycardia between the atria and ventricles. However, tachycardia may not necessarily occur. Radiofrequency ablation can cure it. Simple preexcitation syndrome is not hereditary.

Treatment of Cardiac Preexcitation Syndrome

1. Drug treatment

Drug treatment

Before deciding whether to use drug treatment for preexcitation syndrome, a comprehensive and detailed assessment of the patient with preexcitation syndrome should be conducted. The assessment content and steps are as follows.

(1) Patient’s age of onset

Record the patient's age of onset and number of attacks, paying special attention to the symptoms during the attack.

(2) Number of attacks

Evolution trend of attack frequency and duration.

2. Surgical treatment

Before catheter radiofrequency ablation was developed, surgical treatment was used to treat preexcitation syndrome, and good results were achieved by cutting off or injecting anhydrous alcohol or local freezing bypass, with a cure rate of 80%.

However, since surgical methods are highly invasive and difficult to use on a wide scale, they have been replaced by catheter radiofrequency ablation. Surgical treatment is only used in certain special cases, such as patients with congenital heart disease or acquired heart disease accompanied by preexcitation syndrome who need surgery. At this time, surgical treatment of preexcitation syndrome can be considered at the same time.

3. Radiofrequency catheter ablation

Since 1987, radiofrequency catheter ablation (RFCA) has been used with great success to treat WPW complicated with tachyarrhythmias.

4. Implantable cardioverter-defibrillator

When drug therapy is ineffective or catheter ablation fails, an implantable cardioverter-defibrillator may be considered.
