Is preexcitation syndrome serious

summary

Many people may not know what kind of symptoms pre excitation syndrome is, it is actually abnormal heart, there are some problems, so we still need to know more about some of these problems, let's talk about the severity of pre excitation syndrome.

Is preexcitation syndrome serious

First, pre excitation is an abnormal phenomenon of atrioventricular conduction. Impulses are transmitted down through additional channels to excite part or all of the ventricles in advance, causing part of the ventricular muscles to excite in advance. Patients with preexcitation phenomenon are called preexcitation syndrome (preexcitation syndrome) or WPW (wolf Parkinson white) syndrome, and often complicated with supraventricular paroxysmal tachycardia.

Second: preexcitation is a rare arrhythmia, the diagnosis mainly depends on ECG. No symptoms were found in the patients with preexcitation alone. Supraventricular tachycardia is similar to general supraventricular tachycardia. In patients with atrial flutter or atrial fibrillation, the ventricular rate is about 200 beats / min. in addition to palpitations and other discomfort, shock, heart failure and even sudden death may occur.

Third, there are two conduction pathways between atrioventricular in patients with preexcitation syndrome, which are prone to reentrant and reentrant tachycardia. When tachycardia attacks, most of them propagate backward through the bypass and down the normal channel, so the QRS complex of tachycardia is normal; occasionally, impulses propagate backward through the bypass and down the normal channel, resulting in tachycardia, and the QRS complex is pre excitation.

matters needing attention

So, to a certain extent, preexcitation syndrome is more serious, so once you find the symptoms, you should go to the hospital in time for a special examination, so that you can determine the development of the disease.
