Ask an expert Is pre excitation syndrome a heart disease Is it hereditary Can patients donate blood

It is a kind of arrhythmia, and there are no organic changes in the heart, mainly due to abnormal development of conduction pathways! Rest assured, it won't be inherited! If the seizures are not frequent and do not affect normal life, it is not necessary, the attack is mainly a manifestation of palpitation caused by tachycardia, which can be terminated by pressing the eyeball or carotid sinus, and if you want to **, you can only perform radiofrequency ablation!

It's okay to donate blood!

No special is required for the pre-excitation itself**. Radiofrequency ablation can be done to see if there is atrial fibrillation and supraventricular tachycardia.

You must have been told you had "pre-excitation syndrome" during the ECG. This is the process of cardiac activation signaling, which preemptively excites the ventricles through an abnormally attached pathway between the atria and ventricles. The disease is not hereditary, and if it does not cause discomfort or has mild symptoms, it is generally not needed**.

If it causes your discomfort to worsen, the most common is tachycardia, which can be controlled with medication. If symptoms get worse as you age, surgical interventions such as transcatheter ablation** may be used.

The only effective ** radiofrequency ablation.

Hello, pre-excitation syndrome is the heart has one or more bypass tracts, in layman's terms, it is more than one road, it can make the ventricles or atria excited in advance, when there is no tachycardia attack, and normal people are no different, just do an electrocardiogram can be seen, but some people may have tachycardia, at this time they will feel palpitated, you can go to the hospital for radiofrequency ablation**, you can**, there is no big problem, but if tachycardia is atrial fibrillation, it is dangerous, you must go to the hospital. I hope you find my answer helpful and I wish you good health and happiness.

Typical pre-excitation syndrome, also known as WPW syndrome, is the most common of all types of pre-excitation syndrome, with an incidence of 90% of patients under 50 years of age, more men than women, and men account for 60% to 70%. Most patients do not have organic heart disease, which is caused by abnormal interventricular pathways formed during embryonic development, which can coexist with congenital heart disease or acquired heart disease. It can occur in all age groups, but decreases with age.

An abnormal phenomenon of atrioventricular conduction, in which impulses travel down through additional channels, prematurely excite part or all of the ventricles, causing premature activation of part of the ventricular muscle, and simple pre-excitation is asymptomatic and asymptomatic. Concurrent supraventricular tachycardia is similar to supraventricular tachycardia in general. In patients with atrial flutter or atrial fibrillation, the ventricular rate is mostly about 200 minutes, and shock, heart failure and even sudden death can occur in addition to discomfort such as palpitations.

At a very fast ventricular rate of 300 beats, auscultation of heart sounds can be only half of the ventricular rate on ECG, suggesting that half of ventricular activation does not produce effective mechanical contractions. No special is required for the pre-excitation itself**. In the case of supraventricular tachycardia, ** is the same as general supraventricular tachycardia.

In the case of atrial fibrillation or atrial flutter, if the ventricular rate is rapid and accompanied by circulatory disorders, synchronous direct current cardioversion should be used as soon as possible. Lidocaine, procainamide, propafenone, and amiodarone slow conduction in the bypass pathway, which can slow the ventricular rate or revert atrial fibrillation and atrial flutter to sinus rhythm. Digitalis accelerates bypass conduction, and verapamil and propranolol slow intranodal conduction, both of which may significantly increase the ventricular rate and even develop ventricular fibrillation, so it should not be used.

If supraventricular tachycardia, atrial fibrillation, and atrial flutter seizures are frequent, the above-mentioned antiarrhythmic drugs should be used for long-term oral prophylaxis of seizures. If the drug cannot be controlled, the electrophysiological examination determines that the bypass refractory period is short, or the bypass refractory period is shortened during rapid atrial pacing, or the ventricular rate reaches about 200 minutes during the onset of atrial fibrillation, there are indications for electromedical, radiofrequency, laser or cryoablation after positioning, or surgical shut-off of the bypass to prevent seizures. If the ECG shows that the QRS complex is normal, the P R interval is regular, and the heart rate is about 200 beats, it should be considered as recurrent tachycardia, which is the same as the general supraventricular tachycardia, and can be used for heteropulsion, arrhythmia, ATP or digitalis, etc., if the QRS complex is abnormal and the R R interval is significantly irregular, then pre-excitation combined with atrial fibrillation should be suspected, then arrhythmia, procainamide, or quinidine and propranolol should be used, and heteropulsion, digitalis and ATP are prohibited, Because the latter three can shorten the bypass refractory period and accelerate the bypass conduction, and even ventricular fibrillation occurs.

For patients with frequent seizures of supraventricular tachycardia and significant symptoms, electrophysiologic testing is appropriate to confirm the bypass site and then electroablation, radiofrequency ablation, or surgery**.

Absolutely. Pre-excitation syndrome itself has no symptoms, but it can cause supraventricular tachycardia, and can also be complicated by rapid atrial fibrillation and atrial flutter, inducing palpitations, chest tightness, angina, heart failure, shock, etc.

It is now recognized that pre-excitation is the presence of congenital atrioventricular accessory channels (referred to as accessory pathways) in addition to the normal AV conduction system. Most patients do not have structural heart disease. It is also seen in some congenital and acquired heart diseases, such as tricuspid valve recession, obstructive cardiomyopathy, etc.

Tachycardia can be followed up if there has been no episode, life-threatening tachycardia episodes are severe, and preexcitation syndrome is an interventricular bypass tract, most of which can be ablated by radiofrequency ablation**.

There is a certain danger. It is best to find out the cause and completely eliminate the cause.

Radiofrequency ablation can be done to remove abnormal pathways to the heart. This is a disease that can be a**. Please don't worry too much. There are quite a few patients with similar ones. You can see the following link for more information. I won't copy it.

Condition analysis: Hello, pre-excitation syndrome is the heart has grown one or more bypass tracts, in layman's terms, it is more than one road, it can make the ventricles or atria excited in advance, in the absence of tachycardia attacks, and normal people are no different, just do electrocardiogram can be seen, but some people may have tachycardia, at this time they will feel palpitated, you can go to the hospital for radiofrequency ablation**, yes**, there is no big problem, but if tachycardia is atrial fibrillation, it is dangerous, you must go to the hospital.

Opinions: Pre-excitation is an abnormal phenomenon of atrioventricular conduction, in which the impulse travels down through the additional channel, prematurely excites part or all of the ventricle, causing premature activation of part of the ventricular muscle. People with pre-excitation are called pre-excitation syndrome and are often associated with supraventricular paroxysmal tachycardia.

Pre-excitation is a less common arrhythmia, and diagnosis is based on an electrocardiogram. Currently, the best** option for patients with pre-excitation syndrome type A with recurrent tachycardia episodes is radiofrequency ablation.

Not necessarily, according to your description, it should be asymptomatic. The most common consequence of pre-excitation syndrome is paroxysmal supraventricular tachycardia, the danger is not easy to say, if it is paroxysmal supraventricular tachycardia, the drug is carried out first**, you can choose arrhythmia or amiodarone, if the problem is more serious, you can consider radiofrequency ablation, which is an intervention**, the effect is ideal, and the safety is relatively good. But based on your description so far, you could just put this thing aside and not think about it.

The possibility of sudden death is not completely ruled out, but it is less likely, and it is sudden death as soon as it occurs, which is more difficult than winning the lottery, and you will have plenty of time to deal with this thing. However, as far as the usual diet is concerned, I would like to give you a tip, try not to drink strong tea, coffee, tobacco and alcohol, which can be the cause of arrhythmia. For the rest, I don't think you need to worry too much about it now, just relax!

Pre-excitation syndrome is a condition in which the heart's nerve impulses block abnormally and the heart contracts abnormally. At that time, the palpitations will be automatically relieved, and once the disease occurs, it is relatively difficult, but it is generally not a major problem. Of course, if the symptoms are more severe, there are exceptions. Prevention is recommended.

Pre-excitation syndrome itself is not dangerous, but because there is a bypass tract that is easy to induce supraventricular tachycardia, or atrial fibrillation, atrial flutter, and even ventricular fibrillation, if not treated in time, some serious patients will faint or even die, so if there are frequent attacks, esophageal electrophysiological examination can be performed to determine the location of the bypass, and drugs or radiofrequency ablation can be used**, if there are no symptoms, it can not be treated.
